ci: Prepare for new major branch, remove potel-base from actions (#5003)

### Description

1. Remove `potel-base` from GH action triggers.
2. Let's use the name `major/<version>` for major branches from now on.
Added the pattern to our test workflow files so that we don't need to
add each new major branch to them by hand in the future.
3. Pulled in new test matrix updates as a side effect of regenerating
the YAMLs.

#### Issues

Closes #5004
