<!-- The PR description should answer 2 important questions: -->

### What

We emit a warning suggesting users deprecate
`DataConnectorScalarRepresentation`, however it still has uses outside
boolean expressions, so let's not advise this until it is sensible
advice.

<!-- What is this PR trying to accomplish (and why, if it's not
obvious)? -->

<!-- Consider: do we need to add a changelog entry? -->

<!-- Does this PR introduce new validation that might break old builds?
-->

<!-- Consider: do we need to put new checks behind a flag? -->

### How

Remove a warning.

<!-- How is it trying to accomplish it (what are the implementation
steps)? -->
