Update wordpress monorepo (#21021)

* Fix test errors in extensions/blocks/subscriptions/test/edit.js

  These aren't actually fatal and were present before, but they clutter
  the output when I'm trying to work out what's actually failing.

* No idea what changed, but now there's just one...

  ... <BlockControlsFill/> instead of a <BlockControlsFill> with a bunch
  of content (including a second <BlockControlsFill>). UI looks the same
  as far as I can tell.

* Avoid Gutenberg's "useSpace" hack in the rich-text component

  In WordPress/gutenberg#30244 they added a hack to avoid certain browsers
  activing a button instead of inserting a space. The hack uses
  `document.execCommand()`, which isn't available in jsdom.

  We can avoid it by just not using spaces in the string here, so let's do
  that.
