Cleaning up the repo and removing the runtime

[SantosGuillamot]

This PR aims to clean up the movies repo and remove the code related to the runtime, as we will require the BHE plugin, which should be the one requiring it. As it is right now, it is relying on the build-to-globals branch, as it is exposing the functions needed by the blocks in the window.

Some of the things covered here:

• Require the BHE plugin.
• Remove the runtime and the client-side navigation files, as well as the settings. This should be handled by the other plugin.
• Remove old npm dependencies.
• Change the imports of the store and navigate functions to read from window.__experimentalInteractivity.
• Remove the content-creator folder, as we are generating the content in a different way.
• I also took the opportunity to add the state and the selectors to the SSR files.

I've tried adding the BHE repo to wp-env, but it returns some error. Maybe it's better to wait until we create a downloadable ZIP file, similar to this PR, so we can link directly there.

I solved this issue in the release-action PR, which is intended to be merged in this branch.

I didn't get to review it properly today, sorry. I ll get round to it on Monday 🙂

I thought we could add a disclaimer to indicate that import store with a global is just a temporary solution.

Totally makes sense 🙂 I've just committed the suggestions.

OK, I've pushed a few small improvements and I think we can merge this and https://github.com/c4rl0sbr4v0/wp-movies-demo/pull/20 👍👍👍
