More intuitive channel layer hook

[Archmonger]

Description

This PR is mainly to sync some changes that have been sitting in my local branch for a while.

• Updated the interface for reactpy.hooks.use_channel_layer to be more intuitive.
  • Arguments now must be provided as keyworded arguments.
  • The name argument has been renamed to channel.
  • The group_name argument has been renamed to group.
  • The group_add and group_discard arguments have been removed for simplicity.
• Sync repo files with changes related to reactpy v2
  • Migrate del_html_head_body_transform from reactpy to django-reactpy
• Add logging when RESOLVED_WEB_MODULES_PATH fails to fetch
