Note

Low Risk
Low risk: this is a version bump in config.json plus a corresponding changelog entry; behavior changes are limited to whatever differs in the upgraded engine build.

Overview
Updates the production engine pin from 9.0.22-3832a255c7 to 9.0.23-2c9b279490 in config.json.

Adds a 0.2.77 changelog entry documenting the SingleStoreDB upgrade to 9.0.23.
