Subject: [PATCH] Telegram send image: fix mimetype detection (#7802)

* Add `name` var to BytesIO content to get recognized

Sometimes the python-telegram-bot doesn't recognize the mimetype of the file and looks after a name variable to deduce it. Fixes #7413

* bytesio stream recycle less explicit
