chore(cli): add support for bun package manager

[Robert27]

Since yarn, npm and pnpm are already supported, I see no reason not to support bun.
I tested it via bun patch package and everything worked flawlessly. The magidoc generate was about twice as fast as with pnpm.

We use a bun only Dockerfile where there is no option to add node / npm just to build the docs.

Looks like a no brainier. Thank you for your contribution!
