Revoke and revoked token (#3524)

* i18n: include RevokedToken translation

Note: This message is shown in the "Legacy API Token" field after the user has revoked their legacy token.

* Include alt text so that at least blind users can figure out how to revoke tokens

As a sighted user, I could not figure it out. This gives the blind a chance.
