Does not support @use

@import is being depreciated, @use will replace it. The LSP does not support @use, and since it happens at the top, it makes the rest of linting not work.

I see there is a PR to update it, maybe this PR will fix it: https://github.com/vscode-langservers/vscode-css-languageserver-bin/blob/master/build.js
