use_repo should be called use_repos

[fmeum]

Description of the bug:

The name use_repo doesn't make it clear that the function accepts an arbitrary number of arguments. There are examples of BCR modules with successive, repeated use_repo calls with a single repo name for the same extension proxy, so this is already providing incorrect intuition to real users.

The singular form is also inconsistent with other API such as register_toolchains and register_execution_platforms.

Since there are only ~40 modules today, many of which don't even use use_repo, adding use_repos and keeping use_repo as a deprecated alias for the time being may be doable. Given that this new function will (hopefully) stay with us for a long time, it may very well be worth the effort.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Another reason for I want to bring this up for discussion is the potential to extend the scope of use_repo (#17141 (comment)), in which case use_repos would be a much more fitting name than use_repo.
