Update the WordPress packages to the versions in Gutenberg 11.9 RC

[youknowriad]

This is a subpart of #1804

It's an attempt to try a patch that only contains the minimum required changes for the packages update which should hopefully unblock other patches (FSE infrastructure for instance).

This is lacking two things to be ready to merge:

• The default-editor-styles.css is required for the tests to pass without errors, this file comes with a npm run build but php tests right now are run without the build step. We could account for this in the runtime code but it sounds weird to adapt runtime code to tests.
• The source map error when running npm run build. I'm not sure about this error, we could potentially ignore the failing file for now but I wonder if it highlights a bug in Gutenberg itself and whether we should have a similar check in the plugin as well.

Good idea 🙂

I don't think it's wrong to add a runtime check. We need to support running WordPress from the src directory with no build files.

Also not sure about this. Let's leave it commented out in Gruntfile.js. I'll make a note to come back to this. Probably you are right that there's a bug in Gutenberg's build config.

I've changed the base of this PR to trunk. This is now the default branch going forward. See the original proposal that is finally being put in place.
