docs: def form_ltd_edition_name(git_ref_name=None):
      """Form the LSST the Docs edition name for this branch, using the same
      logic as LTD Keeper does for transforming branch names into edition names.
  
      Parameters
      ----------
      git_ref_name : `str`
         Name of the git branch (or git ref, in general, like a tag) that.
  
      Notes
      -----
      The LTD Keeper (github.com/lsst-sqre/ltd-keeper) logic is being replicated
      here because Keeper is server side code and this is client-side and it's
      not yet clear this warrants being refactored into a common dependency.
  
      See ``keeper.utils.auto_slugify_edition``.
