Docs feedback

How can we improve Base UI documentation?

Would be great to have a native search feature in the Base UI Docs similar to the search within the MUI docs.

Meta discussion:
Should the "Docs feedback" Github issue template apply a Docs tag to the issue?

We'll likely add it at some point before the stable release. No ETA, though.
