docs: improve README files for batch 02 (google_trends → prometheus)

[fivetran-JenasVimal]

Closes RD-1190038

Description of Change

Standardizes README files for connectors #34–66 (google_trends → prometheus) against the README template.

Covers 33 files + creates 1 new README (odata_api had no existing documentation).

⚠️ Note: odata_api/README.md was created from scratch. The connector uses public demo endpoints (TripPin, Northwind) with no credentials required, so no ## Configuration file section was added. Please confirm this is correct or request the section be added.

Testing

README-only changes — no connector code modified.

Checklist

• Tested the connector with fivetran debug command.
• Added/Updated example-specific README.md file, see the README template for the required structure and guidelines.
• Followed Python Coding Standards, refer here

Pull request overview

Updates a batch of Connector SDK example README.md files (google_trends → prometheus) to better match the repository’s README template and formatting conventions, plus adds a new top-level README for the odata_api example.

Changes:

• Adds the fivetran init --template <connector-name> snippet to the Getting started section across the batch.
• Standardizes note formatting (> Note:), heading casing, bullet styles, and code block language hints (notably json).
• Adds/normalizes boilerplate sections like “Additional considerations” and updates “Requirements file” notes about pre-installed packages.

microsoft_intune/README.md:54

• In the Authentication section, the README references get_access_token in test.py, but there is no test.py in this connector folder and get_access_token is defined in connector.py. Update the reference to point to the correct file/function location to avoid broken guidance.

## Authentication

The connector uses a OAuth2 client credentials flow to authenticate with Microsoft Graph API. You will need to provide your Azure tenant ID, client ID, and client secret in the `configuration.json` file. The connector retrieves an access token using these credentials (see `get_access_token` function in `test.py`).

In the Requirements file section, the README states the pre-installed package as requests:latest, but the immediately following note pins it to requests:2.33.0. Please make these consistent (for example, remove the :latest suffix or align with the version shown in the note) to avoid confusion about the runtime environment.

Suggested change

	- Pre-installed packages: `fivetran_connector_sdk:latest` and `requests:latest`
	- Pre-installed packages: `fivetran_connector_sdk:latest` and `requests:2.33.0`

[Copilot]

The H1 title is redundant (it includes "Connector" twice) and doesn’t match the repository template format # <source-name> Connector Example. Consider renaming it to something like # IBM Informix using ibm_db Connector Example (or similar) to follow the template and avoid repetition.

Suggested change

	# IBM Informix Connector using ibm_db Connector Example
	# IBM Informix using ibm_db Connector Example

microsoft_intune/README.md:45

• The configuration.json example uses literal values like "YOUR_TENANT_ID" instead of placeholder-style values (for example <YOUR_TENANT_ID>). Please update these to placeholders so the example can't be mistaken for real credentials and stays consistent with other connector READMEs.

```json
{
  "tenant_id": "YOUR_TENANT_ID",
  "client_id": "YOUR_CLIENT_ID",
  "client_secret": "YOUR_CLIENT_SECRET"

mastertax/README.md:45

• The configuration.json example uses literal values like "YOUR_CLIENT_ID"/"YOUR_CLIENT_SECRET" and generic strings like <certificate string>. Please switch these to the repo’s placeholder style (for example <YOUR_CLIENT_ID>, <YOUR_CLIENT_SECRET>, <YOUR_CERTIFICATE_PEM>, <YOUR_PRIVATE_KEY_PEM>) so the example is unambiguous and consistent.

{
  "clientId": "YOUR_CLIENT_ID",
  "clientSecret": "YOUR_CLIENT_SECRET",
  "crtFile": "<certificate string>",
  "keyFile": "<key string>"

The README says the requirements.txt file is empty, but there is no requirements.txt in the n8n/ directory. Please update the wording to state that no requirements.txt is needed (or add an explicit empty requirements.txt if that’s the intended convention).

[Copilot]

The ## Tables created section lists table names and primary keys, but it doesn’t include column lists/schemas for the created tables (which makes it hard for users to understand what will land in the destination). Please add per-table schema details (columns + primary key) or explicitly reference where the schema is defined in each sub-implementation’s schema() function.

[fivetran-rishabhghosh]

As discussed please point to public facing docs instead of hardcoding versions
