Better discord announcements

[Gewi413]

Some categories need different requirements as to how scores are announced:

• Co-op should display both participants
• meme cat and other non-scored categories don't need a place number
• in general different categories can't be discerned all too well

Proposed fix: each category could have a template string

I doubt the proposed fix is a great option, as that would require adding highly verbose yet purely cosmetic data to the category list of week.json, which would repeat for many categories.

Instead, it's probably best to write the function which generates these updates to consider the already existing category data properties, like the points or coop flags. Essentially, I'm saying that the solution is to add just a couple more "if" statements. To tackle the issue of differentiability, a combination of these flags could be used for assigning a symbol, color, or emoji to the message.
