text: Title: Comma in rendered lists is not localized
  Body: ### Describe the problem
  
  When several values are rendered and joined with `,`, it is not localized. Since https://github.com/WeblateOrg/weblate/commit/0b54da635d614770f53919f469cdfefb6a511abe there is a solution for `format_html_join`, but there are still dozen of places where `", ".join(...)` is used.
  
  ### Describe the solution you would like
  
  Use `format_html_join_comma` whenever the content is shown in the UI.
