Test: Add Opencloud E2E Support with Conditional Page Object Selection and CI Integration

[anon-pradip]

Description

This PR introduces support for running end-to-end (E2E) tests against both oCIS and Opencloud deployments. The main changes include:

• Files Page Object: Added a new FilesPage.js that handles the case where flow for opening file in presentation viewer is a bit different for two servers (opencloud and owncloud). Here, an extra button Open with... is dynamically selected if targetServer is opencloud.

• Conditional Page Object Selection: Updated the step definitions to use openMDFileInPresentationViewer from files page object to open file in presentation viewer

• Config Update: The configuration file now reads TARGET_SERVER from the environment, defaulting to ocis if not set.

• CI Workflow Enhancement: The GitHub Actions workflow now includes separate steps for running E2E tests against oCIS and Opencloud, each with the correct environment variable, ensuring the right tests and selectors are used for each deployment.

• Documentation: Updated the README with instructions on how to run E2E tests for both oCIS and Opencloud, clarifying the use of the TARGET_SERVER environment variable.

Motivation and Context

Previously, the E2E tests only supported oCIS, and selector differences in Opencloud caused failures. By introducing a dedicated page object for Opencloud and selecting it conditionally, we ensure reliable test execution for both platforms. The CI changes guarantee that the correct environment and selectors are used for each server type, improving test coverage and maintainability.

How Has This Been Tested?

• test environment:
• Locally and CI

Screenshots (if appropriate):

1. On oCIS: Direct option to open file in presentation viewer after just clicking in context menu

2. On Opencloud: Click on context menu button -> Click on Open with... -> Click on Open in Presentation Viewer
