Link interactivity (e.g. :hover) styles

[MaggieCabrera]

In order to test WordPress/gutenberg#41786 and preparing for when that one gets merged we should implement link hover (and probably focus?) styles on our themes. I think we should start with:

• Blockbase Blockbase: move link pseudo states to theme.json #6156
• Blank canvas
• Block Canvas Block canvas: replacing button :hover CSS by theme.json definition #6486
• Curator Vivre: move link pseudo states to theme.json #6150
• Livro
• Skatepark
• Stewart
• Pendant Pendant: replacing CSS with theme.json settings for link elements #6179

And follow up to clean up CSS from any other themes that are using it.

There's a PR for Archeo already open.

Hope you don't mind I updated the title and desc to include that you might also consider implementing :focus just for a11y reasons 🙇

@madhusudhand @mikachan looks like only Blank Canvas is remaining on this list, any others we've missed?

Looking through our other themes, it looks like we may also need to update Livro, Skatepark and Stewart. I'll add them to the above list, they shouldn't take long to update.

In a conversation with @MaggieCabrera and @pbking we decided to remove this from the board until the pseudo selector feature lands WordPress core for two main reasons:

• If we remove the CSS and the theme user doesn't have the Gutenberg plugin activated the link behavior will change and the link interactivity will no longer work.
• If the user has Gutenberg activated the link behavior will be the same but the user will not receive any extra value because the UI to configure the link interactivity doesn't exist yet.
