actions: set job timeouts to 30 minutes

The default timeout is 6 hours, which is too long for autospec's needs.

We could probably lessen the timeout even more, but I want to account
for the possibility of variable network speeds and future bundle size
increases, which may increase runtime of the `docker build` phase of the
testing steps. Long term, it would be nice to ship a prebuilt container
in Dockerhub for autospec CI testing like mixer-tools does.
