Update CI workflows for documentation build and deployment

[Borda]

This pull request updates the documentation-related GitHub Actions workflows by simplifying job names, removing unnecessary matrix strategies, and improving environment variable handling. It also updates the naming conventions for better clarity and maintainability.

Workflow job and naming updates:

• Renamed the test docs workflow from "🧪 Docs Test WorkFlow 📚" to "Test Docs Build" for clarity, and changed the job name from docs-build-test to docs-build in .github/workflows/test-doc.yml. [1] [2]
• Renamed the deploy job from deploy to docs-build-deploy in .github/workflows/publish-docs.yml for consistency.

Simplification and cleanup:

• Removed the matrix strategy for Python version selection in both workflows and set the Python version directly to "3.10", streamlining the configuration. [1] [2]
• Eliminated the GitHub App token creation and direct installation of mkdocs-material-insiders via a token, simplifying dependency installation in the docs deploy workflow.

Environment and deployment improvements:

• Updated git configuration to use the ${{ github.actor }} for user name and email, improving traceability of workflow actions.
• Moved the MKDOCS_GIT_COMMITTERS_APIKEY environment variable into the env section for both deploy steps, making environment variable management clearer.
