👷 Update workflows to v3.0.0, restore Release Drafter & tidy README

[frenck]

Proposed Changes

(Describe the changes and rationale behind them)

Updates all hassio-addons/workflows references to v3.0.0, restores the standalone Release Drafter workflow, lowers the permissions of the CI & Deploy workflows, removes the lock and stale workflows, and tidies up the README badges.

Workflows

Upstream hassio-addons/workflows v3.0.0 (#291) moves Release Drafter back out of base-ci.yaml into a standalone reusable workflow. Because CI no longer drafts releases, it no longer needs write access:

• Re-added .github/workflows/release-drafter.yaml — it carries the contents: write + pull-requests: read permissions needed for drafting releases (triggered on push to main).
• ci.yaml: contents: write → contents: read, and removed pull-requests: read.
• deploy.yaml: same permission reduction on the ci job; the deploy job is unchanged.
• Bumped every hassio-addons/workflows reference (base-ci, base-deploy, release-drafter, labels, pr-labels) to v3.0.0.
• Removed the lock.yaml workflow completely.
• Removed the stale.yaml workflow completely.

README

• Removed the architecture (aarch64/amd64) badges.
• Removed the Discord chat and Community Forum badges.

Walkthrough

Upgrades reusable workflow pins to v3.0.0, refines job and top-level permissions for CI/deploy workflows, adds a release-drafter workflow, updates label workflow pins, and adjusts README badges.

Changes

Workflow version and permission updates

Layer / File(s)	Summary
CI workflow permission tightening and v3.0.0 upgrade .github/workflows/ci.yaml	Top-level permissions changed: contents: write -> contents: read, removed pull-requests; packages: read and security-events: write retained. Reusable base-ci.yaml pin bumped to v3.0.0.
Deploy workflow permission adjustments and v3.0.0 upgrade .github/workflows/deploy.yaml	Both ci and deploy jobs update their permissions blocks and bump referenced hassio-addons base workflow pins from v2.0.6 to v3.0.0. CI job explicitly enables security-events: write while keeping actions: read; deploy job retains packages: write.
Release drafter workflow addition .github/workflows/release-drafter.yaml	New workflow added to run on pushes to main, grants contents: write and pull-requests: read, and reuses the external release-drafter workflow pinned to v3.0.0.
Label-related reusable workflow pins updated .github/workflows/labels.yaml, .github/workflows/pr-labels.yaml	Both label-sync and PR-label workflows updated to use hassio-addons/workflows pins at v3.0.0.
README badge updates README.md	Badge block updated to show GitHub Actions, maintenance, and GitHub Activity shields; removed architecture and Discord/forum shields and their reference link definitions.

Poem

🐰 I hopped through YAML lines so neat,
Pinned v3.0.0 and trimmed the suite,
Badges polished, labels aligned,
Release drafts wake when main’s inclined,
Pipelines prance with lighter feet. 🎉
