Bumps actions/setup-python from 3 to 4.

Release notes

Sourced from actions/setup-python's releases.

v4.0.0

What's Changed

• Support for python-version-file input: #336

Example of usage:

- uses: actions/setup-python@v4
  with:
    python-version-file: '.python-version' # Read python version from a file
- run: python my_script.py

There is no default python version for this setup-python major version, the action requires to specify either python-version input or python-version-file input. If the python-version input is not specified the action will try to read required version from file from python-version-file input.

• Use pypyX.Y for PyPy python-version input: #349

Example of usage:

- uses: actions/setup-python@v4
  with:
    python-version: 'pypy3.9' # pypy-X.Y kept for backward compatibility
- run: python my_script.py

• RUNNER_TOOL_CACHE environment variable is equal AGENT_TOOLSDIRECTORY: #338

• Bugfix: create missing pypyX.Y symlinks: #347

• PKG_CONFIG_PATH environment variable: #400

• Added python-path output: #405 python-path output contains Python executable path.

• Updated zeit/ncc to vercel/ncc package: #393

• Bugfix: fixed output for prerelease version of poetry: #409

• Made pythonLocation environment variable consistent for Python and PyPy: #418

• Bugfix for 3.x-dev syntax: #417

• Other improvements: #318 #396 #384 #387 #388

Update actions/cache version to 2.0.2

In scope of this release we updated actions/cache package as the new version contains fixes related to GHES 3.5 (actions/setup-python#382)

Add "cache-hit" output and fix "python-version" output for PyPy

This release introduces new output cache-hit (actions/setup-python#373) and fix python-version output for PyPy (actions/setup-python#365)

The cache-hit output contains boolean value indicating that an exact match was found for the key. It shows that the action uses already existing cache or not. The output is available only if cache is enabled.

Hm, this change introduced a python-version, which is supposed to be passed as an argument for the action setup. The action people write

The python-version input is optional. If not supplied, the action will try to resolve the version from the default .python-version file. If the .python-version file doesn't exist Python or PyPy version from the PATH will be used. The default version of Python or PyPy in PATH varies between runners and can be changed unexpectedly so we recommend always using setup-python.

I would add a version, but I'm not sure which one to set. Maybe just

- uses: actions/setup-python@v4
  with:
    python-version: '3.x'

?

Looks like actions/setup-python is up-to-date now, so this is no longer needed.
