🪲[Fix]: Fix linting issue for main (#24)

This pull request updates the Action-Test GitHub Actions workflow to improve its automation and linting capabilities. The most important changes are grouped below.

Workflow triggers:

• The workflow will now also run on pushes to the main branch, in addition to the existing triggers (workflow_dispatch, pull_request, and schedule).

Job steps and linting improvements:

• The step that used the PSModule/GitHub-Script@v1 action to list files and commit documentation changes has been removed, simplifying the workflow.
• The Lint documentation step now uses super-linter/slim@v8.1.0 instead of a pinned commit from v8.2.0, and several new environment variables have been added to enable broader validation (VALIDATE_NATURAL_LANGUAGE, VALIDATE_ALL_CODEBASE, USE_FIND_ALGORITHM).
