Add rtzr plugin to optional dependencies

[zach-iee]

Allow users to install the RTZR STT plugin as an optional dependency rather than manually specifying the package.

Users can now run: pip install livekit-agents[rtzr]

This brings rtzr in line with all other livekit plugins, which are available as optional dependencies.

Poem

🐰 A package hopped in with cheer,
A tiny plugin cozy and near,
It found its place within the tree,
Now workspace links hum merrily,
Hooray — a hop, a bump, a cheer!
