Removes a feature flag gate on a CSSStyleSheet polyfill and bumps the Shopify protocols version.

Highlights

The bootstrap module's CSSStyleSheet.replaceSync polyfill no longer checks the MobileBridgeNext flag before running, so it now applies unconditionally rather than only for that flagged rollout.
The SHOPIFY_PROTOCOLS constant in _utilities.js was bumped from 0.38.10+52074793 to 0.38.11+c048218d.
