[MINOR][TEST-ONLY] add a test timeout to kill before GitActions

This commit adds a timeout to surefire to allow the tests to timeout,
with a log message and stack trace rather than allowing github Actions
to kill the CI job.

When Actions kill the job, we do not know which tests are running or
blocking, while if we kill surefire we will.
