Support mail address is broken

[misl6]

Description

The documentation claims:

If you need assistance, you can ask for help on our mailing list:

User Group : https://groups.google.com/group/kivy-users Email : kivy-users@googlegroups.com

However, you can't directly email that address (perhaps until you have joined the group). It gives an error by reply email (mentioned in this comment and reproduced by me with a throwaway account.

The documentation should not mention the email address, and stick to the URL.

A PR (which also does a refactor) has been done on buildozer repo: https://github.com/kivy/buildozer/pull/1722#discussion_r1362594418
