Ability for non-admin users to request workspace user invites

Previously, non-admin workspace user were not able to send user invites. To speed up the process of adding users but keep similar permissions, non-admin users can now request a user invitation.

When a user clicks the +Invite button but does not have admin permissions, a modal now appears with the message "Send request to invite user?" + prompt to enter an email. This request is sent to workspace admins to approve/deny the user invite.

Workspace admins can find user approvals in the "Manage Users" section of Workspace Settings (in the profile picture dropdown).
