chore: Prevent CI from running Dredd against parsing service
chore: Prevent CI from running Dredd against parsing service

This creates a chicken-egg problem because we cannot update the docs
because some changes is not deployed. But we cannot deploy those changes
as there are no docs.

I don't believe it makes sense to run dredd against a service here on CI.
