Everything since 3.5.2 (see #3301) can use it;
it's now present in all non-EOL MacOS XCode versions

It turns out, macos-14 has XCode 15 rather than 16 as advertised in Github docs

ubuntu-20.04 is being retired by Github
tar_gz is mainly to verify URLs, OS version doesn't matter

Now that ubuntu-24 is out of beta at Github

Since for ubuntu_build, we only use one OS version
and the changes between versions are not as drastic as with MacOS,
it seems safe to have it upgrade automatically.

Only CPython scripts use bundled dependencies for MacOS and two alternative tarballs

`::set-output` is deprecated as per https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Github has finally released those as free and retired macos-11

since we're only interested in the output when something goes wrong

* CI: Bump OS versions

Github released ubuntu-22.04 and macos-12 from beta
and deprecated ubuntu-18.04 and macos-10.15, due to dropping by 2013.

* CI: clean up installed packages

Shims from executables bundled with some older Anaconda releases
cause MacOS script check jobs to hang at the end

probot/no-response has been retired and no longer runs

Now the setup is to add to both rc and profile:
1) set PYENV_ROOT
   (can do it unconditionally -- since if you change it,
   you need to update all places anyway since any of them can be run first)
2) Add `pyenv` to PATH if not already there
3) eval "$(pyenv init -)"

Not a breaking change, old setup will continue to work.

Now that Travis check has been removed from the repo
