[FEATURE] Add Command-line Tab Completion to AsyncAPI CLI

[gambhirsharma]

Why do we need this improvement?

While using the AsyncAPI CLI for the first time, I found it frustrating to repeatedly use the --help flag to look up commands. To address this, I proposed adding a feature to improve the user experience.

I initially started a discussion, but since it hasn't received any responses, I decided to create an issue instead. I also checked for duplicate issues and couldn't find any, so I went ahead with opening this one.

How will this change help?

This feature will significantly improve the user experience when working with the AsyncAPI CLI by:

• Making the CLI more discoverable - users can press tab to see what commands are available
• Reducing cognitive load - users don't need to memorize all commands and options
• Speeding up command entry - especially for long command names or complex option combinations
• Bringing the CLI in line with industry standards - most popular CLI tools support tab completion
• Improving accessibility for new users - making it easier to explore the tool's capabilities

Screenshots

No response

How could it be implemented/designed?

As the AsyncAPI CLI uses the oclif framework, adding tab completion is straightforward using the @oclif/plugin-autocomplete plugin.

This had been on my mind for a while now. Found out about https://github.com/oclif/plugin-autocomplete a while back but didn't get a chance to play around with it.

I think this will be pretty cool to have. WDYT? @Souvikns @AayushSaini101
