Remove esm-only warning when serverModuleFormat is esm

[onemen]

From docs for serverdependenciestobundle:

This can be useful when consuming ESM only packages in a CJS build
Here's how you would be able to consume those packages in a CJS app without having to use dynamic imports

When we configure remix with serverModuleFormat: 'esm' we don't need to use dynamic imports for ESM only packages

Do you think it is possible to remove the warning in this case?

Is this the warning Remix is getting rid of?
