ci: run BrowserOS test suites on PRs (#514)

* ci: run browseros tests on pull requests

* refactor: rework 0320-github_action_for_tests based on feedback

* refactor: rework 0320-github_action_for_tests based on feedback

* chore: add CI artifacts to .gitignore

* fix: remove mikepenz/action-junit-report to fix check suite misattribution

The JUnit report action creates check runs that GitHub associates with the
CLA check suite instead of the Tests check suite, causing test reports to
appear under "CLA Assistant" in the PR checks UI.

Remove the action and rely on job status + step summary + artifact upload
for test result visibility.
