Description 📋

• What:
  This PR introduces accessibility testing to our test suite to ensure our application meets accessibility standards. The key changes include:

  • Integrated accessibility tests into the test suite.
  • Created a GitHub Actions workflow to automatically run accessibility tests on each push/PR.

• Why:
  With this addition, we can proactively catch and fix accessibility-related issues, improving the overall user experience.

• How:

  • Ran tests locally and confirmed most accessibility checks passed as most tests are failing (a follow-up PR will address the failing accessibility tests).
  • Verified that the GitHub Actions workflow successfully executes the tests.

Checklist ✅

• All tests pass locally
• Added tests (if applicable)
• Documentation updated (if applicable)

Looks mostly good!

I only think we need to update the requirements page as it has all the things (with versions pinned) that is not necessary

Hey Jay, I would love to merge this only when I've been able to fix the failing test locally. Just to be cautious 😂

That makes sense for me. I will leave open.
