This keeps only themacos-14 jobs, which run on Apple Silicon M1, and removes themacos-13 jobs, which ran on x86-64. This relates to the commented discussion in#1944. There would also be the option of keeping some of them, but removing all of them decreases the workload the most while also being the simplest.

It also uses the labelmacos-latest instead, which is currently equivalent tomacos-14.

Some information about the situation withmacos-latest and the benefit of using it is presented in the second commit message.
That these jobs really are running on macOS 14, and more importantly that they are really running on ARM64, can be verified by examining the output of "Set up job" step.Here's an example.

Other operating systems' jobs continue to run on x86-64 machines (and none on ARM, yet). Only macOS jobs are removed.

This change leaves Python 3.7 without any macOS test job. That is probably okay, since it has been end-of-life for some time, and it remains tested on Ubuntu and Windows.

Use the macos-latest label rather than macos-14

Currently they are the same. The macos-latest label will move tolater versions automatically in the future, like the ubuntu-latestand windows-latest labels that we are already using.In this repo, the macos-14 label had been used originally becauseit was added before the migration of macos-latest to be macos-14was completed. Seegithub/roadmap#926. Itwas kept for clarity of constrast with the macos-13 jobs that werealso in use, some for the same Python versions.Now that the macos-13 jobs have been removed inc2bbaf4, themacos-latest label can be used here without confusion.
