refactor: introduce @validate_body_root_model

[leafty]

Add @validate_body_root_model which is a drop-in replacement for Sanic's @validate when validating a RootModel or a model deriving from it.

The decorator should be replaced by @validate once sanic-org/sanic-ext#198 is fixed.

thanks for this!

I have two bugfix PRs open in sanic (one addresses this issue) for over a month now, without any reply. So don't have too high hopes of them fixing this any time soon on their end...
