ref(bun): Ensure bun is latest for local tests (#16244)

I noticed that my bun version locally was old, leading to weird test
issues.
Now, our install script will ensure this is the latest version. On CI,
we already test against the latest version.

(Noticed this because bun 1.0.2 which I had installed reports itself as
Node 18.5.0 which lead to ESM warnings)
