    Fix master failing on generating requirements (#8885)
    
    By default github actions checks out only latest commit but in order to
    see if there are any changes since the last readme generated
    we need to see the whole history so we need to fetch it all.
    
    We also skip generating the new README in case there is only one
    commit in the history since the last release. The nature of readme
    generation is that the commit with the README itself will never
    be in the list of commits for the previous release so there is
    always at least one commit more than the one listed in the readme.
