Switch from yarn to bun

Yarn is a bit of a pain, the traditional yarn does not support import path such as workspace:*.
So I had first switched to yarn berry (canary -> 4.2.5) but it seems to be very inconsistent with there lock file, now using both yarn.lock and a couple .pnp files 🤯

And this seems to cause some weird incompatibility with vscode, as prettier on save and vs code does not detect the dependencies as installed anymore...

I tested bun last night, and it seems to work as we need-it out of the box and be faster
