build: Upgrade WordPress packages (#66)

* build: Upgrade development dependencies

* build: Upgrade @wordpress/icons

* build: Upgrade @wordpress/base-styles

* build: Upgrade @wordpress/preferences

* build: Upgrade remaining WordPress packages

Most of these depend upon one another and must be upgraded together.

* fix: Ensure block canvas background color renders behind child margins

The `display: flex;` declaration was removed in core:

WordPress/gutenberg#66706

Its removal causes the post title's margin to extend beyond its parent
boundaries, which caused the background color to not render the entire
height of the editor.

* refactor: Improve class name accuracy

Rename classes to match component file names.

* build: Downgrade eslint

The latest version is incompatible with Gutenberg ESLint configuration.

* Revert "build: Upgrade development dependencies"

This reverts commit 147de47.

* build: Upgrade non-ESLint development dependencies

Postpone ESLint upgrades due to various configuration conflicts.

* build: Upgrade eslint-plugin-react-refresh

* build: Upgrade @wordpress/eslint-plugin

* fix: Ensure block canvas fills its parent container width

This resolves a regression introduced from changes in the following PR.
Ideally we resolve this issue in Gutenberg core, rather than overriding
the styles within GutenbergKit.

WordPress/gutenberg#66706

* fix: Denote auto-draft status

If Apple and Google allowed programmatic focus of interactive elements
in web views, this would ensure the post title field is focused for new
drafts. However, Apple and Google require user interaction--e.g.,
taps--for the virtual keyboard to display.

Regardless, denoting the auto-draft status is likely still worthwhile.
