fix: ignore broken pipes when writing to terminal

[BapRx]

I registered a lot of repositories and I'd like to be able to pipe the output of multigit to other programs to process the output. For example:

❯ multigit list | head -n1
/Users/baprx/example-repo

thread 'main' panicked at library/std/src/io/stdio.rs:1123:9:
failed printing to stdout: Broken pipe (os error 32)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

With this PR I'm able to do this.
Broken pipes in Rust CLI tools is a well known issue that affects a lot of tools. cf rust's issue tracker: rust-lang/rust#46016

Changes:

• fix: use writeln instead of println to catch broken pipe errors.
• chore: switch to colored lib instead of colored_markup which is maintained and more straightforward.

Thanks for the PR - I'd be willing to consider this if it were two PRs - one with the writeln change and one with the colored change. I maintain colored_markup so I am less concerned about maintenance.

I don't see how to split this PR since the calls which produce the broken pipe are println_markup from colored_markup. Please tell me if you see a way to do so, I'm not experienced with Rust 😁
