Fix model version argument conflicting with clap version argument

[DrChat]

Both clap and this example provide a version argument, which causes a panic at runtime when arguments are parsed.
The easiest way to fix this is to rename the model's version argument.

Thanks for looking into this!

Weirdly I am not having this issue on my end, do you mind sharing how you are providing the argument and what error you're getting?

You have to run it with this command line to see that error:

> cargo run --features wgpu,llama3 --example chat -- --help

Command llama-burn: Argument names must be unique, but 'version' is in use by more than one argument or group (call `cmd.disable_version_flag(true)` to remove the auto-generated `--version`)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Ahhh ok I see! Didn't try --help so I never stumbled upon that 😅

Thanks for the response and fix!
