`tinyglobby` at `0.2.10` (what we use now) is slow on shallow files, but
the latest version `0.2.12` is fast due to this PR
https://github.com/SuperchupuDev/tinyglobby/pull/69/files.
This PR updates both the js and esbuild plugins to use the newest
versions, but also adds `tinyglobby@^0.2.12` to our root `package.json`
so we get the speed increase right away. I removed `fast-glob` in our
repo scripts and replaced it with `tinyglobby`.
## Current Behavior
Asset handling is slow for shallow files like `LICENSE` but is fine for
scoped patterns like `src/**/*.ts`.
## Expected Behavior
Asset handling should be fast for shallow files.
