Make UV_GIT_LFS active by default on some url

### Summary

When installing some on our dependencies by URL, we need to set {{UV_GIT_LFS=1 uv run...}}.

Would it be possible to have this option definied somewhere arround the URL, to specify that a given git+https needs LFS, and another one does not.

Ideas:

```
uv add git+lfs+ssh://git@github.com/...
```
