Nice @awnion. Thank you. Look forward for it to be pushed!

@awnion How can I test it with Bash on Linux?

I like that you did it in a clean and efficient way and I think that this is a good addition to SUI CLI tooling.

@awnion How can I test it with Bash on Linux?

If you have Rust and Cargo set up, you can generate the completion file from my branch. E.g like this:

1. Generate the file:

   cargo run --bin sui -- completion --generate bash > /etc/bash_completion.d/sui

   (You might need to run this with sudo since /etc/bash_completion.d/ is a system directory. If you don't have permissions, you can try directing the output to ~/.local/share/bash-completion/completions/sui instead.)

2. Make it active:
   Once that file is in place, either open a new terminal session or run source ~/.bashrc (or equivalent).

3. Test it out:
   Type sui (with a space) and hit Tab twice. You should immediately see the list of sui subcommands appear.

Let me know if you run into any issues with the file path!

Tested with docker run --rm -ti ghcr.io/awnion/sui_cli_completions/sui_cli_bash_completions:latest
The autocompletion works fine.
