Reorder emoji following standard order

Problem

Right now emoji are ordered alphabetically in the Award Emoji dropdown. This is non-standard and makes them hard to find because they're not in the order people are used to, which also groups them by similarity.

Proposal

Reorder them following the standard Unicode Emoji Order.

This makes them hard to find because they're not in the order people are used to, which also groups them by similarity. I propose we reorder them following the standard Unicode Emoji Order.

Steps

• Programmatically reorder in the emojiCategoryMap based on v12.1 of the emoji-ordering.txt and emoji-ordering-rules.txt
• Verify that the re-order approach is compatible with the existing emoji sprite. This is typically stored via local cache and we don't want to introduce any weird lookup issues during render.

Implementation Plan

• FE/BE to sort this out
