fix(linux): Fix packaging GHA

For some reason with some PR builds we got an incorrect base ref. This
change makes better use of the information that GitHub provides and so
should work around the problem.

Merge branch 'feat/core/9468-marker-normalization-epic-ldml' into feat/core/9450-backspace-epic-ldml

- separate some element API tests from the actual tertiary test.  Tests were failing because of now-correct implementation.
