Low Risk
Simple version bump and changelog update with no code or logic changes; risk is limited to any runtime behavior differences introduced by the new engine build.

Overview
Bumps the configured SingleStoreDB engine/server build in config.json from 9.0.20-360ebd4468 to 9.0.22-3832a255c7.

Adds a new CHANGELOG.md entry for release 0.2.76 documenting the SingleStoreDB 9.0.22 version.
