audio_path and friends are not paths

[dhdaines]

If you try to use a path for audio_path, video_path, etc, then you get a very unfriendly validation error:

data.list[function-after[data_is_valid(), DataSource]].0.manifest.audio_path
  Input should be a valid URL, relative URL without a base [type=url_parsing, input_value='/assets/', input_type=str]
    For further information visit https://errors.pydantic.dev/2.4/v/url_parsing

Pydantic's validation definitely wants these to be URLs with a scheme, host, etc. I wonder about the wisdom of making these HttpUrl since in reality they are nearly always going to be relative (or absolute to the deployment root) paths. Plus it's in the name!

It looks like you can get around this by making them Union[HttpUrl, str] but then you don't actually get any validation since Pydantic will always fall back to str (and they end up being strings in the JSON anyway).
