Add inputs options to change location of versions-manifest.json

[ganadist]

Description:
Currently, setup-python action has hard coded location of versions-manifest.json from actions/python-versions repo.
And this repo supports prebuilt binaries for recent ubuntu distributions only.

If location can be changed by action users, setup-python can be used for other linux distributions such as RHEL, CentOS and others.

• Tested : https://github.com/ganadist/setup-python-demo/actions/runs/5848513383/job/15855890593
  • with my versions-manifest.json on Rocky Linux 8
  • I used ubuntu 18.04 binaries for Rocky Linux 8, because it seems binaries are compatible with it.
