[UI] Adds support for CTRL key as a modifier for Query shortcuts

[renato-bohler]

This PR includes a simple UI enhancement, adding support for the CTRL key as a modifier on the Query page (for Windows and Linux users).

The feature was originally added on #7359, but only included support for the event.metaKey modifier, which maps to the ⌘ key on MacOS, but really can't be used as a modifier for Windows/Linux users.

	const handleQueryInterfaceKeyDown = (editor, event) => {
	// Map Cmd + Enter KeyPress to executing the query
	if (event.metaKey == true && event.keyCode == 13) {
	handleRunNow(editor.getValue());
	}
	// Map Cmd + / KeyPress to toggle commenting the query
	if (event.metaKey == true && event.keyCode == 191) {
	handleComment(editor);
	}
	}

With the implementation on this PR, MacOS users could use either the Cmd (⌘) or Control (^) as modifiers.

Closes #12086
