## Summary

The [current scripts docs
page](https://docs.astral.sh/uv/guides/scripts/) doesn't include detail
on how to use a custom package index when setting up a script. I believe
this might be because it didn't use to work (see astral-sh#6688 ) but it now does
(thanks for that, by the way! 😄)

Given it's a useful feature, I suggest adding a quick example to the
scripts page, with the details of authentication, etc. left to the main
`indexes.md` doc.

I'd also suggests that this closes astral-sh#6688, though it doesn't actually add
that feature - that appears to have already been done :)

## Test Plan

No testing is needed, I think!
