python-docker: Update to 7.0.0

Upgrade Notes:
 - Removed SSL version (ssl_version) and explicit hostname check
 (assert_hostname) options
   - assert_hostname has not been used since Python 3.6 and was
   removed in 3.12

   Websockets
   - Websocket client is only required to use attach_socket(container,
   ws=True)

 2023)

 unhealthy)
 - Add pause option to container.commit()
 - Add support for bind mount propagation (e.g. rshared, private)
 - Add filters, keep_storage, and all parameters to prune_builds()
 (requires API v1.39+)
