Prevent last owner from leaving the team

[jankeromnes]

Currently in Teams & Projects:

• Owners can remove Members form the team
• Anyone can leave a team

However, if you're the last Owner of the team and you leave, the team has no owner anymore.

Also, if you're the last person on the team, the team will become empty (and unless someone still has a working invite link, the team name/slug is "burned").

From #4571 (comment):

Some of the possible solutions here:

1. Keep the Leave option as is and on click trigger a toast notification with an error message explaining that you cannot leave because you are the only remaining owner of the team. Needs: Add toast component in notifications #3530.
2. Keep the Leave option as a disabled option (red-300) and show a tooltip on hover explaining why you cannot perform this action. See screenshot A below.
3. Disable the more actions button (gray-400) and show a tooltip on hover. See screenshot B below.

A. Disabled dropdown option	B. Disabled dropdown button

@jldec: Cannot schedule issue - issue does not belong to a team. Use /team to specify one.

Or option 4: change the "Leave" option to "Delete team" when they are the last owner of the team. @gtsiolis @jldec

I would prefer some visible notification like a toast (not just a tooltip) OR

5. change red Leave Team to a non-clickable, gray Leave Team with a message right below it saying "The last remaining owner of a team cannot leave the team."

@jldec I think you should create a fresh issue with a clear actionable description of your preferred solution. This ticket (especially the title) still sounds very unclear.

Updated with clearer title.

• The main priority for this is to prevent the last owner from leaving the team.
• My preferred design for how best to do this would be to disable the action inside the dropdown and provide a visible explanation inside the dropdown as well (not tooltip)
