Enable Group block in production

[jbinda]

Updates Gutenberg so the Group block is available in production.

Gutenberg PR: WordPress/gutenberg#20004

To test:

• Run the app without metro running
• Start a new post
• Verify Group block is visible in the block picker
• Select the Group block
• Verify it is working as expected:
  • Try to break it
  • Use try portrait & landscape modes
  • Try nesting it more than expected
  • Check if the navigation button on FloatingToolbar works
  • Check if AppenderButton is visible when Group is selected
  • Check if AppenderButton is show as placeholder when Group is unselected
  • Check if AppenderButton open the Inserter after press (when Group block is empty and when it already has some nested blocks)
  • Move the block between other ones inside a Group and check it works correctly
  • Move the whole Group block between another Group blocks in RootList
  • Try to use Ungroup button on Toolbar
  • Remove the block
  • Add one again
• Save as draft
• Open your draft and check the Group block is shown correctly

PR submission checklist:

• I have considered adding unit tests where possible.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

We don't need to add this since we are already mentioning it in gutenberg-mobile release notes.

We don't need to merge this PR. Let's just use it for testing.

Looks good. 👍Great work WordPress/gutenberg#20004 (review)

[pinarol]

@jbinda I have one request from you. Could you add some of the test from this PR to this file under "Group-1" title? It is not super urgent, we can do that in 2 weeks. But it'll be very helpful for upcoming sanity tests. Some test cases can really benefit from screenshots, in that case let's follow the method we used for other tests that has links provided like: "Gallery block - Add Gallery Caption - steps". Please ping me if you have any questions. Thanks!

[jbinda]

@pinarol Sure I will handle that

@chipsnyder thanks for testing and review ! :)
