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

steps:
  - uses: actions/checkout@v3
