fix(cli): Style CLI errors in init mode

[epage]

By rolling back tracing-subscriber for now

Fixes #4731

Thanks a lot for you investigation!

It'd probably be better if we just = pin that to the older version and add a comment explaining why, we've done the same in #4708.

Also although it's okay to close the original issue with this, I'm not sure if a new follow-up issue should be made regarding the future development.

Otherwise LGTM!

Is there an issue against tracing-subscriber?

@djc Yes, the regression seems intentional and for which we have an upstream issue at tokio-rs/tracing#3369.

Update: It seems that UV has been hit by this as well (astral-sh/uv#15843) and what they did was to (at least for the moment being) forget about color codes in such occasions.

Yes, I think it makes sense to open an issue for tracking the ability to upgrade tracing-subscriber

One approach I was playing with (but hit a time box so switched to this) is to extract from rustup_mode.rs the clap error handling and reusing it for setup_ode.rs.
