Fix some mangled JS syntax in tooltip.html (#93231)

## About The Pull Request

So some source code pre-prettier was missing a few commas, which led to
it looking a bit odd post-prettier.
I found the old source block, fixed the issues, ran prettier again, and
it's, uh, prettier now.

## Why It's Good For The Game

Consistent code makes for less confusing changes (this entire debacle
started because I didn't know why some variables were in parentheses and
others weren't)

No user facing changes.
