Fix CI for 1.12

[penelopeysm]

CI has been silently bumped from 1.11 to 1.12 (I suppose an official release is soon to follow). This PR:

• Adds one set of 1.11 tests
• Disables Mooncake on what are now the 1.12 tests, since it doesn't work yet
• Disables testing on version: 'pre' since there are no prerelease versions of 1.13 and it just tests on 1.12, which is now redundant.
• Move the benchmarking + Enzyme CI jobs to 1.11, since they use Enzyme and/or Mooncake which don't work on 1.12
