Generate a run annotation when test environment fails to start

When product tests fail, they produce an report, which is used to
generate GitHub Actions annotations so it's easier to know the failure
cause, without having to browse the failed job logs. Generate a similar
annotation when the test environment fails to start, which is a common
failure cause.

The original error is still produced, so it can be looked up in logs,
for anyone that's used to doing it.
