Hi, since Symfony 6.2 there's a design issue that bothers me with the toolbar: the hover effect seems "wrong" when hovering one of the right blocks.

This PR fixes the following issues on hover:

* removes green background color
* removes the extra box shadow
* moves the remaining box shadow to the left
* moves the non-radius border from left to right
* uses CSS variables for -green color
* fixes non visible Symfony CLI icon on small screen
* uses same style for green status (bottom colored line instead of full background)
