Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Merge "Reformat auth_url based on the ID API version."
  - Reformat auth_url based on the ID API version.

    No longer raising an OSCredsError when the auth_url does
    not end with a 'v' + some number. Additionally, the auth_url
    will be massaged to remove any 'v' + num from the end of
    the URL and generate its own version value based on the ID
    API version configured.
