AutoTester2 / CI required checks name changes

[achauphan]

Opened PRs prior to #15371 merging will be notified that their branch must be updated via a normal commit or rebased on develop to receive the new jobs for CI.

The refactor of our CI AT2.yml in #15371 is planned to be merged later today. This refactor will change the names of the GitHub Actions (AutoTester2) jobs which are used for checking that a required CI job ran and passed.

This has potential to disrupt opened PRs that haven't been updated to receive the changes merged into develop, causing "missing" required checks from GitHub Actions which will prevent the PR from being ready-to-merge.

• Framework: refactor AT2.yml to use a reusable workflow #15371

Below are the expected job name changes as a result of the refactor work:

Old Name	New Name
gcc14	gcc14 / build-test
gcc12-openmpi4	gcc12-openmpi4 / build-test
openmp	openmp / build-test
clang19-openmpi4	clang19-openmpi4 / build-test
oneapi2024	openapi2024 / build-test
cuda12	cuda12 / build-test
cuda12-uvm	cuda12-uvm / build-test
framework-tests	framework-tests / build-test

This discussion will be updated with its current progress.

develop branch protection rules have been changed to check for the new names and #15371 has merged.
