Description

In the Edit Widgets page, the Settings panel toggle button shows a wrong icon when 'Show button text labels' is on.

It appears the Edit Widgets page is a bit behind and maybe a little overlooked.
To start with, it should fullly support 'Show button text labels', like the two other editors.
Anyways, when 'Show button text labels' is enabled in the post editor, the widgets editor shows a wrong icon instead of text.

icon={ showIconLabels ? check : icon }

I'm not sure why the Complementary area toggle is supposed to show the 'check' icon when showIconLabels is true. There's no apparent reason for that, unless I'm missing something. Cc @tellthemachines
It seems to be there since #24304

I'm not even shure the other editors use the ComplementaryArea and ComplementaryAreaToggle this way.
