Address eslint react-hooks/purity error on sidebar component

[davbrito]

The following snippet was triggering eslint react-hooks/purity error:

ui/apps/www/registry/default/ui/sidebar.tsx

Lines 664 to 666 in ed9d593

	const width = React.useMemo(() => {
	return `${Math.floor(Math.random() * 40) + 50}%`
	}, [])

This rule violation can introduce issues with the react compiler.

I replaced the useMemo with an useState as suggested in the react docs site.
