Add ResBaz Festival to "events" (WIP)

[hidyverse]

I created some of the basic text but I'm being held up by wanting to include our 2024 flyer (which hasn't been finalized).

I'm also wondering about the randomAvatars @alex-r-bigelow. Will the following work without me doing something else with the character string here? Do I need to assign folks to a group to be called by this tag?

```{ojs}
randomAvatars("ResBaz Festival");

Sorry about that; the randomAvatars thing looks for team names in data/people.json (and that gets auto-updated with public GitHub profiles based on our teams every time we merge a branch to main)...

... so if you want the latest data in your local repository, there's a weird step where we have to manually download / replace data/people.json with whatever is live at https://researchbazaar.arizona.edu/data/people.json

I'll add something about this to the README in a bit.

Also, I think I need to add some flex styling so that teams with lots of avatars don't run beyond the margin! Will commit some more fixes in a sec...

Okay, done with my tweaks; let me know if there are further issues.

Your additions look great; once you've got the 2024 flyer, I'd vote to go ahead and merge! Thank you!

Hm even after adding a draft flyer, it does not load. I maybe did something wrong there.
