Bug(CI): CI duplication and messiness

Describe the bug

I'm seeing duplicates in CI after: https://github.com/python/pythondotorg/pull/2852, specifically in https://github.com/python/pythondotorg/pull/2868's lint CI runs (runs 2x).

I don't like this and it's confusing to me why we have this problem in the first place because none of my other projects have ever had this weird double CI run thing.

Review the CI changes introduced by pull request #2852 and compare the pull request #2868 checks, especially the duplicated Lint runs and Terraform Cloud entries. Confirm which workflows are triggering each check and consider the issue complete when pull requests produce no duplicate CI checks.
