Frontend: Add a copy-to-clipboard button in the code snippet in the component tab

Context

1. In the designs, the code snippets for the components did not have a copy-to-clipboard button so I did not add one. If we want that functionality, we can also create a follow-up!

Proposal

• 🔗 Figma prototype
• 👉 Design tab
