Reduce verbosity of "simple" error messages

[halostatue]

Mise error messages are verbose because of the facility used to print them:

$ mise self-update
Error:
   0: mise is installed via a package manager, cannot update

Location:
   src/cli/self_update.rs:39

Version:
   2024.8.4 macos-arm64 (2024-08-02)

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.

I understand that it's nice to use the same output facility for all error messages, but in case of "simple" messages like this, I would expect to see something more like:

$ mise self-update
mise is installed via a package manager, cannot update

This is especially noisy because it happens on command-line rendering if there is an untrusted .mise.toml file:

Error:
   0: Config file is not trusted.
      Trust it with `mise trust`.

Location:
   src/config/config_file/mod.rs:214

Version:
   2024.8.4 macos-arm64 (2024-08-02)

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.

Here, this message is both too verbose (I don't need location or version or the backtrace message) and insufficiently verbose (which config file is untrusted?; it could be ~/.config/mise/config.toml if I edited it recently). I would expect to see, instead:

Error: Config file `path/to/file/.mise.toml` is not trusted.
Trust it with `mise trust`.

I think there are errors that could happen where the location and version might be useful — but for the most part, I don't think that information is helpful to the casual user of mise.
