[docs]: The copy button on installation code block shows a dropdown

[karimkod]

Feature description

In the current docs, the installation code blocks contain a clipboard icon, when clicked it shows a dropdown to choose the package manager used.
I think for UX purposes, we can either have a different icon (a chevron down), or have a separate dropdown to choose which package is needed and the copy button will just copy.

No response

Additional Context

This has made me go back to the docs page to re-do the copy from the dropdown, since the clipboard icon is deceptive.

I think this is coming from : https://github.com/shadcn-ui/ui/blob/main/apps/www/components/copy-button.tsx

Open for discussion and ready to PR if there is agreement!
