fix: Tweak release-plz config to handle dirty files. (#433)

bindings/ruby/bin/console and bindings/ruby/bin/setup show up
as dirty to release-plz and causes it to fail to update.

As a workaround, set allow_dirty to true to enable update.
However ensure that no dirty files are published by setting
publish_allow_dirty to false.

Also default to not publishing any packages except regorus.
