Update app.py

no need to explain edit count requirement, so as to avoid misunderstanding like https://commons.wikimedia.org/wiki/Commons_talk:Video2commons#c-Susbush-20240925123600-RZuo-20240925113700

would be better if the message includes a link to https://commons.wikimedia.org/wiki/Commons:Autoconfirmed_users but i dont know how.
