`bun why` (like `yarn why`)

### What is the problem this feature will solve?

I like using `yarn why <package-name>` to see what version I have and where it came from.

### What is the feature you are proposing to solve the problem?

`bun why <package name>`

### What alternatives have you considered?

Switching from Bun to `yarn` as the package manager.

PS – wow this thing is fast. Mind blown.
