Add determine-runner job to test.yml

New workflows are running on Buildjet runners, however, they
are not available in personal forks and it is useful to run test.yml
in fork, that is why this commit introduces determine-runner job,
which checks if we are in fork and changes runner to ubuntu-2204 which
is available everywhere
