[Console] [CCI] console Audit. Unused ul html element.

[curq]

Describe the bug

After doing audit of console plugin. I noticed <ul> element and its scss class that were never used and that they don't seem to do anything.

OpenSearch-Dashboards/src/plugins/console/public/styles/_app.scss

Lines 80 to 90 in a8ace28

	// SASSTODO: This component seems to not be used anymore?
	// Possibly replaced by the Ace version
	.conApp__autoComplete {
	position: absolute;
	left: -1000px;
	visibility: hidden;
	/* by pass any other element in ace and resize bar, but not modal popups */
	z-index: $euiZLevel1 + 2;
	margin-top: 22px;
	}

OpenSearch-Dashboards/src/plugins/console/public/application/containers/editor/legacy/console_editor/editor.tsx

Line 234 in a8ace28

<ul className="conApp__autoComplete" id="autocomplete" />

Expected behavior
No redundant custom styling or native html elements

Dashboards Version
2.7.0

Plugins

Console plugin

Additional context

We can see from the comments left by previous developers in the .scss file that they also didn't find if the removed element and styling were used anymore.
