[🔥AUDIT🔥] Fix mistype of update-browserslist-db package name (#1427)

🖍 _This is an audit!_ 🖍

## Summary:

I mistyped the package name, and it's hard to test Github Actions without landing them first. :'( 

Issue: "none"

## Test plan:

`npx update-browserslist-db@latest` works and matches what's in the YML now!
