Does this preclude us from moving these into a separate namespace later? (as discussed elsewhere)

It's kind of weird to have this in warn_config_settings?

We want to make it easier for users to try the build backend, so we allow using the build backend without requiring
UV_PREVIEW=1. Instead, we only print a note about the preview status of the build backend. This improves using packages with the uv build backend with other PEP 517 frontends that don't have uv's--previewflag.Closes #11819
