in custom-roles.yaml.10 file, is there some typo?

[yixuan178]

Anyone using this repo should run the following for OSP11:
  mv custom-roles.yaml.10 custom-roles.yaml

Or the following for OSP10:
  mv custom-roles.yaml.11 custom-roles.yaml

before deploying, in addition to other changes as required for
their environment.">Have two versions of custom-roles.yaml for OSP10 or OSP11</a>

osp10 should be the mv custom-roles.yaml.10 custom-roles.yaml ???
any typo here?

thanks,
Eugene
