UI: Update ScrollArea with radix

[cdedreuille]

What I did

In this PR we are improving the underlying ScrollArea component to move from overlayscrollbars to @radix-ui/react-scroll-area. The API is much easier to use, resulting in less code to maintain and it is up to the latest standards in term of accessibility.

This is using the exact same API as before and should have not impact on the UI as it is an absolute object position on top of everything.

@ndelangen @valentinpalkovic Sorry I had to create a new PR. Any chance you could review this one again?

@ndelangen I'm using the same styles as the next version. theme.textMutedColor with opacity of 0.5. When you hover it goes to 0.6 opacity. But in this version I'm pushing it to 0.8 for better visibility.

This is how it look on the sidebar for example.
