Subject: [PATCH 1/2] MNT: do not let one Python version cancel the other in
 the slow matrix

#1084 added fail-fast: false to the main test matrix while this was open, so
the only half left is the slow one. Same reason: 3.10 failing says nothing
about 3.14, so cancelling it costs a result and saves nothing worth having.

Subject: [PATCH 2/2] MNT: retry the VTK tests on SIGSEGV, not only on macOS
 SIGBUS

#1084 retries the animation tests when they die on 138, which is SIGBUS on
macOS. Counting the last 40 Tests runs, the crash was 139 eight times and 138
twice, so the common case fell straight through the retry. Linux SIGBUS is 135
rather than 138, so that missed as well.

Also sets fail-fast: false on the slow matrix, which #1084 left out. 3.10
failing says nothing about 3.14, so cancelling it costs a result and saves
nothing worth having.
