Administration: Sync admin-ui Page header accessibility backport from Gutenberg.

Mirror the changes from Gutenberg PR WordPress/gutenberg#78002 (which
backports WordPress/gutenberg#77617 and WordPress/gutenberg#78001 to
the `wp/7.0` branch) into the auto-generated wordpress-develop bundles
for the Connectors and Font Library admin screens.

Two of the three accessibility issues raised in the ticket are
addressed by this sync:

* Page heading is now an `h1` instead of an `h2`. The bundled
  `Header` component's default `headingLevel` is bumped from 2 to 1,
  and the now-redundant explicit `headingLevel: 1` overrides at the
  Connectors and Font Library route stages are dropped.
* The inappropriate `<header>` landmark inside the page's `region`
  landmark is removed by dropping the `render: <header />` prop on
  the Stack wrapping the page header, eliminating the nested `banner`
  landmark.

The third issue (full-white body background) still needs to land
upstream in Gutenberg per the latest comment on the ticket.

Bundles updated for both the readable and minified outputs of:

* `src/wp-includes/build/routes/connectors-home/content.js`
* `src/wp-includes/build/routes/connectors-home/content.min.js`
* `src/wp-includes/build/routes/font-list/content.js`
* `src/wp-includes/build/routes/font-list/content.min.js`

The `version` hash in each `content.min.asset.php` is bumped to the
md5 of the new minified bundle so cached browser copies are invalidated;
the next official Gutenberg sync will overwrite these with the build
pipeline's canonical hashes.
