Temporary disable android auto

[Florian14]

Android Auto feature has been inherited from Element, but The PlayStore has rejected the version for Android Auto for this reason:

Login Credentials
In order for us to review your app for compliance with Developer Program Policies, we will need you to provide valid login credentials for your app.
If users need credentials to access your app, please provide all appropriate credentials via Play Console.

There were no recent changes about the login flow, the provided credentials are still valid and there is no specific relation with Android Auto, so the fastest way to solve it is to disable the feature (which was not present in Tchap-v1)

2.0.3 will disable Android Auto support, to unblock the release of Tchap 2.0, we'll re-enable it later.
