Show channel rename keybinding in the context menu (#4155)

Deals with `Can't rename channels from keyboard` #product note.
We actually already have the action binding to rename the context menu
entries, but had no label entry to show that.

Release Notes:

- Added a channel rename keymap label on the collab panel context menu
