fix(ui): fix sidebar height

[Botato300]

Description

Fix the sidebar height. It's a small detail, in the images you can see the differences. The sidebar was moving a few pixels down because of the header's height, so I calculated it in css: 100svh - header height and that's it!

Before

After

Validation

Just go to any page that has the long sidebar, like /learn. For some reason, it redirects me to nodejs.org instead of a localhost url, so you can go to /en/about/get-involved/events and add several <li> items to the sidebar, and you'll be able to reproduce it!
