Describe the bug

Looks like in the NuGet package description we're missing the new controls we've added in 7.1: ContrainedBox, MetadataControl, RichSuggestBox.

Probably some of the behaviors from the behavior package.

We should add them to the package description (without going over 4000 char limit).

Steps to Reproduce

Steps to reproduce the behavior:

1. Open VS Package Manager
2. Find Toolkit package
3. look at description

Expected behavior
