Revert "Merge branch 'bmarjanovic/update-graphql-gems' into 'master'"

The MR !114605 (merged) updated SASSC and graphiql gems, which leads to compilations in the asset build. The full asset build never ran in the MR, because we do not consider Gemfile updates to have an impact on the "Asset pipeline".

Purpose of revert

gitlab-org/quality/engineering-productivity/master-broken-incidents#1177 (closed)
