feat(wrangler/cli): add @bomb.sh/tab completions

[AmirSa12]

This PR introduces tab completion functionality for the wrangler cli, improving developer experience by allowing shell(zsh, powershell, fish, bash) autocompletion for commands, options, values, and flags. This also comes with npm, pnpm, yarn and bun copmpletions! ( npm exec ... , pnpm ... ) With this PR, users can navigate available commands, options and values more efficiently and faster with speeding up workflow.

Awesome stuff, thanks so much @AmirSa12 🙏

I've left a comment regarding the completions setup, could you take a look? 😄

Also could you advise on how I can manually test this feature? 🙂
(is there a setup required, etc...)

[dario-piotrowicz]

I think that taking the values from the docs and using them here is a bit problematic (as we'd also need to keep them in sync, etc...)

Could you try to instead use the experimental_getWranglerCommands function to dynamically get the information you need and setup the completions from that? 🙂
