[Bug]: Missing export for `Menu` component and types in core package

[edimitchel]

Describe the feature

Hi Reka UI team,

I've noticed that the Menu component is not exported in the index.ts file of the core package. I had to manually add the export to use the component in my project.

Additionally, I need access to the injectMenuContext method to handle specific cases of menu opening. This functionality is crucial for my use case, and I believe it should be part of the exported API.

Is there a specific reason why Menu and methods like injectMenuContext are not exported by default? If this is an oversight, could they be added in a future update? I'm happy to provide more details or contribute a PR if needed.

Thanks for your amazing work on Reka UI!
