Use Bookworm for CI.

At least for now, it seems that newer Debians (and the compilers they ship) find warnings that we don't want to deal with.

I've bumped the CI time allowance for this repo from 1 hour to 2. Hopefully this fixes this.

It looks to me like it's stalled on a test:

16:15:14 0:02:42 load avg: 0.75 [256/404] test_plistlib
16:15:14 0:02:42 load avg: 0.75 [257/404] test_poll
16:15:25 0:02:53 load avg: 0.63 [258/404] test_popen
16:15:25 0:02:53 load avg: 0.63 [259/404] test_popen2

I must admit that I'm not sure what to do about that... CCing @Eddy114514.

No, my network stalled! It's still running.

No, my network stalled! It's still running.

I am wondering if this is a situation similar to #36, as it was also running for a long time.

@ltratt Sorry for confusion, I was wondering if this stalling is similar to #36 situation, but since it merged, I suppose it is ok for now.
