Description

• Update the specifications page of the Select component to match the new options icon sizing.
• Minor code refactors:
  • Now the component uses the Resize Observer API for the width of the Listbox.
  • ThemeProvider is only used in the parent component (Select.tsx). Sub-components don't have it anymore to avoid additional renders.
  • Adjustments based on the above changes.
