Site editor: WP logo focus style regression

[afercia]

Description

The focus style of the WP logo in the Site editor is now barely visible and not standard.

This is the focus style on WordPress 6.5:

This is the focus style on Gutenberg trunk:

The WP logo uses a custom implementation of the focus style. I think the regression comes from the fact the transform scale CSS is now applied to the link element itself while previously it was applied to the inner div element.

Step-by-step reproduction instructions

• Go to the Site editor.
• Tab to the WP logo.
• Observe the focus style is barely visible and not standard.
