Codegen Android: update Docker configuration to support codegen (#30268)

Summary:
Pull Request resolved: #30268

This addresses the following CI failure:
https://app.circleci.com/pipelines/github/facebook/react-native/6847/workflows/36d59aab-bc4a-4d21-9ce1-a8348e71aea3/jobs/173669

The problem was missing directories because we didn't copy the relevant ones for docker build.

In addition:
* The codegen depends on `invariant`, but didn't specify the dep in package.json. This fixes it.
* Also ask Metro to ignore buck-out

Note that this will depend on docker image v1.0.5 (to be released later) to fully build. v1.0.5 will need to install `rsync`, see this patch: https://gist.github.com/fkgozali/1d8cae92a5bc521e0f2e4f275008db93. With my test image (of 1.0.5 local build), I got the docker build to pass:

```

```

To test with a custom local docker image:
* https://docs.docker.com/get-started/ (install the Mac client)
* git clone https://github.com/react-native-community/docker-android
* Make the local change then create the fake v1.0.5 image:
  * `docker build --tag reactnativecommunity/react-native-android:1.0.5 .`
  * Run the image from Docker Mac client
* Then build RN docker test pasted above.
