Feat: update border radius variables

[marcoambrosini]

@susnux @ShGKme I've been asked to update and tidy this up, could you please tell me if this configuration makes sense to you? Also variable names

@susnux @ShGKme about defult.css and defaulttheme.php, let's decide which file we write documentation in and move it all there?

Currently, they are documented in the documentation: https://docs.nextcloud.com/server/latest/developer_manual/html_css_design/css.html

As @ShGKme mentioned documentation should all go to the developer manual part of the docs, if you ask because of deprecation comments, then I would add those to both files to make it clearer for server developers.

I added some docs to both files too for now because that's where most people are going to look

Looks good, please ensure that you add this to the app upgrade guide in the developer documentation as soon as possible so that app developers can adjust their apps best before Nextcloud 30 release :)

@susnux I also updated the value of body container radius, that ok?
