github: bump actions/setup-python from 3 to 4.2.0

[dependabot]

Bumps actions/setup-python from 3 to 4.2.0.

Release notes

Sourced from actions/setup-python's releases.

Add check-latest input and bug fixes

In scope of this release we add the check-latest input. If check-latest is set to true, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, the version will then be downloaded from python-versions repository. By default check-latest is set to false. For PyPy it will to try to reach https://downloads.python.org/pypy/versions.json

Example of usage:

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-python@v4
    with:
      python-version: '3.9'
      check-latest: true
  - run: python --version

• Resolved logs for python-version and file inputs: actions/setup-python#465
