Editor: Update of npm packages after 6.4 RC3.

This update includes the following fixes reported after RC3:

* Regression: [WordPress/gutenberg#55858 Fixes patterns not working anymore as a post template for custom post types].

Scenario: When creating a new post for any custom post type registered with its "template" argument set to a pattern.

For this scenario, the pattern template no longer renders in the post editor or the frontend with 6.4, whereas it did render properly in 6.3.2.

This package update resolves the console error raised:
{{{
Uncaught TypeError: select(...).getCurrentTheme() is undefined 
}}}
which restores the rendering of the pattern template.

* Regression: [WordPress/gutenberg#55859  Fixes positioning and styles for the new lightbox's trigger] introduced in 6.4.

Follow up to [57048], [57034], [56987], [56961], [56849], [56818], [56816].

Props renathoc, rajinsharwar, richtabor, joen, mikachan, hellofromTonya.
Fixes #59411.
