Trigger on pull_request workflows on all branches (#174)

[konveyor-ci-bot[bot]]

• Trigger on pull_request workflows on all branches

There are TIER 0..2 on pull request workflows that should check the PR with CI. These workflows were targeted only to main branch that lead to not being executed on release-* branches. Updated to trigger on all branches.

Fixes: https://github.com/konveyor/go-konveyor-tests/issues/173
