Visually inconsistent diagrams in Matchmaking Guide

In the [Matchmaking Guide](https://open-match.dev/site/docs/guides/matchmaker/#game-services-architecture), the diagrams on the page shift where components are and how they're coded.

In the first diagram, the Match Function is clearly indicated as a customized component in pink along with the Evaluator, both of which are outside the Open Match system. In the second diagram, the Match Function is now gray and inside the Open Match system. Redis is also gray and inside the Open Match system, but was missing in the first diagram.

I would prefer to see a single consistent diagram in terms of placement/colors that contains all components. Each use of the diagram can then have different arrows to indicate which components are being used and how data is flowing for the given step being discussed.
