Subject: [PATCH] feat(route): add user likes activity for Hugging Face
 (#21838)

Introduces a new route to fetch and display user likes activity from Hugging Face, including links to liked repositories and their types.
The route is accessible via '/activity/:user/likes' and supports various repository types such as datasets, spaces, papers, and collections.

This is done by parsing the JSON provided through the HuggingFace API.
E.g.: `https://huggingface.co/api/users/dotwee/likes`
