Playground: implicitly opened modules

[fhammerschmidt]

This one is a prerequisite for the v11 docs so that we do not need to have open RescriptCore in every example.

I am not sure if the api version change is necessary btw. Maybe it can still be v3 since we are at the experimental stage for 11 still?

This looks good to me! What does the API version number do?

[cknitt]

Looks good to me, too! 👍 Could you rebase and add a CHANGELOG entry?

I think it's just to make it easier for the playground to decide which features/libraries can be used. https://github.com/rescript-association/rescript-lang.org/blob/master/src/common/CompilerManagerHook.res

The apiVersion number should always be raised whenever the API has received some feature addition or breaking change. As you already stated correctly, the CompilerManagerHook differentiates between different versions to gracefully support all compiler bundles.

Then I guess this PR is ready to merge as-is!
