Removing yourself from an organization should require a confirmation dialog

[fnetX]

• Gitea version (or commit ref): 1.14.3 + 1.15-dev
• Database (use [x]):
  • MySQL
• Can you reproduce the bug at https://try.gitea.io:
  • Yes, https://try.gitea.io/org/will-leave-owners/teams/owners = no longer accessible for me
  • No

Description

A user on Codeberg reported perse accidentally left the "Owners" team of an organization, as this requires no confirmation, and thus the whole organization with no chance, to regain access after a single mistaken click.

As many other things do require confirmation, and these buttons are quite easy to hit ("Leave", or removing the wrong member), this should have a confirmation dialog IMHO, too.

Thank you for considering a fix. ✌️
