Child theme.json: update test to better capture that childs can update single parts in isolation

[oandregal]

Follow-up to #35459

Update so we test that single parts can be overridden by the child while untouched parent sections remain the same.

@oandregal, you might want to rebase on the latest trunk. The React Native iOS issue got fixed recently.

I already did but it seems it's a different error in this case? cc @geriux

Tests are passing for me locally 👍

Thanks for the ping, I restarted the job but it failed again, I'll investigate this. 👍

Rebased again to see if that clears the new error out.

ok, got a new one:

Run sudo xcode-select --switch /Applications/Xcode_12.5.1.app
xcode-select: error: invalid developer directory '/Applications/Xcode_12.5.1.app'
Error: Process completed with exit code 1.

which I also see happening in trunk for a commit after the XCode update https://github.com/WordPress/gutenberg/runs/3940696898

Sorry for that, it looks like the propagation of the Github action changes are taking more than expected so we are hoping to fix it in this PR.
