Use `@use` instead of `@import` in scss (or reduce import duplication)

[Samuel-Therrien-Beslogic]

See Sass: @import is Deprecated

I landed on this article after noticing that the entire global app CSS was being written multiple times in the page source on Cannopeum.

Changing @import '../App.scss' to @use '../App.scss' as * everywhere should the trick to have access to the variables.

Yikes!

Fixed !

However the small fix applied above wasn't sufficient. Whilst rsuite is no longer loaded multiple times, bootstrap and our own style still are

This is making re-rendering of CSS unecessarily slow and debugging especially annoying.
