ci: hotfix: disable test exclusion by tags

Many tests and CI activties are being missed by excluding tests
mistakingly when running twister.
This is visibile when you change one or more tests in kernel/ for
example, twister does not run those tests that have changed at all and
marking the PR as tested and ready to be merged.

Temporary fix for #40235.
