Remove temporary src/plugins/eui_utils eslint overrides

[spalger]

In order to move forward with #49244 we needed to disable some rules in src/plugins/eui_utils. We need to remove the related overrides and get the package passing these rules pretty soon.

// .eslintrc.js
{
  files: ['src/plugins/eui_utils/**/*.{js,ts,tsx}'],
  rules: {
    'react-hooks/exhaustive-deps': 'off',
  },
},

Ok so you're talking about the last line of

kibana/src/plugins/eui_utils/public/eui_utils.ts

Lines 42 to 45 in 6f79046

	useEffect(() => {
	const s = getChartsTheme$().subscribe(update);
	return () => s.unsubscribe();
	}, [false]);

I hadn't written that part of the plugin and not really sure what it does. You are welcome to change whatever needs to change.
