[docs] Place a copy button next to the import for MUI icons

[GabriFila]

• I have searched the issues of this repository and believe that this is not a duplicate.

Summary 💡

In the current MUI docs, in the icons section, there is not the possibility to quickly copy the import statement for an icon. It would be good to have a button to quickly copy the import statement.

I would be very happy to add it myself.

Examples 🌈

This is the current version

I would imagine something like this, or maybe with the button before the import. I'm open to suggestions and guidelines.

Motivation 🔦

I believe it is not necessary, but it can be useful. I always like websites that provide me with shortcuts.

Thank you!

@GabriFila Does #23850 solve the issue? https://next--material-ui.netlify.app/components/material-icons/

[GabriFila]

Yes, very sorry did not see it. I only looked at the issues not the PRs.

[oliviertassinari]

Great, thanks for the confirmation.
