Merge pull request 'ci(m9): upload UI-test xcresult on failure for a11y triage (#126)' (#127) from feat/126-xcresult-on-failure into milestone/m9-monterey

UI failures on the self-hosted runner are hard to triage from stdout
alone — the xcresult already contains the a11y hierarchy snapshot and
screenshots. Upload Logs/Test when build-and-test fails.
