Build/Test Tools: Remove the requirement to clone/build Gutenberg.
This iterates on the changes from [61438] by removing the need to:
- Check out the WordPress/gutenberg repository at the pinned hash.
- Run
npm install within that checkout.
- Run
npm build within that checkout.
Instead, the build script will now download a prebuilt zip file published to the GitHub Container Registry by a GitHub Actions workflow recently merged to the Gutenberg Repository (related PR: https://github.com/WordPress/gutenberg/pull/75844).
This also removes redundant code responsible for:
- Copying files from the
gutenberg directory to the appropriate locations during the build script in favor of using grunt copy.
- Modifying built files to replace specific text, such as
sourceMappingURL, in favor of grunt replace.
The remaining files within the tools/gutenberg directory have been renamed to remove gutenberg from the file names. Since these are already nested in a gutenberg directory, that was redundant.
Since the intention of the pinned value for the repository in the package.json file is to specify a full-length commit hash, ref has been renamed to sha. In Git ref encompasses branches, tags, and commit hashes, so this hopefully makes it more clear that something like branch-name should not be used.
Follow up to [61438], [61439], [61458], [61492], [61677], [61867].
