chore: CI improvements.

This commit features several CI improvements:

- Clearer naming of CI files, pipelines, and jobs.
- Adds "website-test.yml" to test website changes on PRs.
- Removes duplicative tests on `main` after equivalent tests
  on PRs, given that PRs can only merge with passing tests.
