fix: remove ValidScopedCSSClass from recommended config

Temporary fix while performance issues are resolved.

The check re-parses every {% stylesheet %} tag in the theme on every
save, causing severe lag in VS Code on larger themes (reported in
#1179 — "Getting code actions from Shopify Liquid" hangs for several
seconds on save in v3.11.2).

The check remains available as an opt-in rule in the :all preset. It
will be re-added to :recommended once the language-server performance
work in progress (PR forthcoming) lands.
