ruff_db: make `Diagnostic::print` use a non-mutable borrow 

Now that we don't need to update the `printed` flag, this can just be an
immutable borrow.

(Arguably this should have been an immutable borrow even initially, but
I didn't want to introduce interior mutability without a more compelling
justification.)
