Restore conditional cache disabling for Node 22

Preserve the original behavior from master where yarn cache is disabled for Node 22 due to V8 bug in 22.21.0 (nodejs/node#56010).

Before: cache: yarn (always enabled)
After: cache: ${{ steps.translate-matrix.outputs.node-version != '22' && 'yarn' || '' }}

This ensures Node 22 runs without cache while Node 20 uses cache as intended.
