QA Steps

1. Log into an account that has a Workspace in NewDot. You can create one if you don't already have one by clicking on the green plus in the bottom left. It doesn't need to have a bank account set up.
2. Go to Workspace's Settings -> People
   
3. Invite a new user if you are the only member in the workspace. After you do. Select that user and try to remove them. Verify that confirm modal that pops up has the new copy (in the screenshots below).
