## Summary

The example in the docs for adding a git source with `--branch` fails
because `main` doesn't exist.

```sh
uv add git+https://github.com/encode/httpx --branch main
# error: Git operation failed
#   Caused by: failed to fetch into: /Users/manzt/.cache/uv/git-v0/db/4c0b1441d92956e1
#   Caused by: failed to fetch branch `main`
#   Caused by: process didn't exit successfully: `/usr/bin/git fetch --force --update-head-ok 'https://github.com/encode/httpx' '+refs/heads/main:refs/remotes/origin/main'` (exit status: 128)
```

This PR changes the example to the default branch for httpx, `master`.
