Changing checksums for downloads from github.com/.../.../archive

• cfr. https://github.com/easybuilders/easybuild-easyconfigs/issues/5151
• known broken checksums fixed in https://github.com/easybuilders/easybuild-easyconfigs/pull/5162
  • impact was fairly minor since only some easyconfigs include checksums
• best way to deal with it in the future?
  • just update checksums again if it occurs again? easy via --inject-checksums --force-download...
  • mention use of --force-download in error message on failing checksum?
  • trust that GitHub fixes it in the future...
