    This might cause duplicate entries if the user did not specify in all-lowercase.
    Also, it will not overwrite custom configuration, which might make the installation fail.

    If the secrets were not provided, get them from a grain/generate and save them there.
    This avoids
      a) calling the gitea binary in the app.ini template (`gitea generate secret SECRET_KEY`)
      b) and special-casing to avoid regenerating those secrets every run.

    The INTERNAL_TOKEN has a special format, but it can be configured to be read from a separate file.
