Add the following actions for use while calling: `Mute`, `Deafen`, `ShareProject`, `ScreenShare`, `LeaveCall` We were also interested in adding push-to-talk functionality for mute, but that will go in a followup PR Release Notes: - Call actions (mute/screenshare/etc.) can now be bound to keys and run from the command palette. --------- Co-authored-by: Ben Kunkle <ben.kunkle@gmail.com> Co-authored-by: Ben Kunkle <ben@zed.dev>
