use explicit setup-python versions over implicit expose- (Cherry-pick…

… of #21568, #21582) (#21668)

The project is currently using a mix of the GitHub supplied
`setup-python` action and `pantsbuild/actions/expose-pythons`. On GitHub
managed runners they behave similarly:
* `setup-python` will install a version of Python if missing, or add it
to the PATH if already present at the expected location (managed runners
historically have multiple Pythons baked into the image)
* `expose-pythons` will add all Python's at the expected GitHub location
to the PATH. (Which ones is up to GitHub.)

So today the invocation of `setup-python` followed by `expose-pythons`
is redundant.

Consolidating on `setup-python` let's us be explicit about expected
versions (more like the ARM image) and reduces the number of custom
actions the project manages while still making multiple Python versions
available.

NOTE: The awkward double newlines in the final yaml are a pre-existing
issue

See #21552 for some history regarding the `setup-` vs `expose-` actions.
