LinkControl: remove unused CSS flex properties

[afercia]

Description

While reviewing all the CSS order and *-reverse properties used in the editor I spotted a couple CSS declarations for the LinkControl that don't do anything and seem a leftover.

gutenberg/packages/block-editor/src/components/link-control/style.scss

Lines 343 to 348 in 06cfe8c

	.block-editor-link-control__drawer {
	display: flex; // allow for ordering.
	order: 30;
	flex-direction: column;
	flex-basis: 100%; // occupy full width.
	}

Both order: 30; and flex-basis: 100%; would take effect if this element was a flex item. However, the parend isn't a flexbox congtainer, it is display: block;;.

The browser dev tools shows these two properties have no effect:

I thik the whole ruleset is now a leftover of a previous implementation in the original PR and can be safely removed.

Step-by-step reproduction instructions

• Add a link.
• Open the link settings UI.
• In the browser dev tools, select the element with CSS class block-editor-link-control__drawer
• Observe the flex and flex item properties set on the element don't do anything.

Re:

Nothing that display: flex; allows for ordering of the childen.
