Get rid of matrix_mautrix_signal_configuration_permissions

While it's kind of nice having it, it's also somewhat raw

Having a good default and not even mentioning it seems better
for most users.

People who need a more exposed bridge (rare) can use
override the default configuration using
`matrix_mautrix_signal_configuration_extension_yaml`.
