Replace the unmaintained "atty" crate with "is-terminal"

The "atty" crate is unmaintained [0] and also causes a low severity
GitHub advisory (GHSA-g98v-hv3f-hcfr; only affects windows though) [1]:
> A Pull Request with a fix has been provided over a year ago but the
> maintainer seems to be unreachable.
> Last release of atty was almost 3 years ago.

The "clap" crate already switched to "is-terminal" [2] so we can simply
use the latter without having to pull in additional dependencies.
The "is-terminal" crate can also be considered a successor [3]:
> This crate is derived from the atty crate with PR 51 bug fix and PR 54
> port to windows-sys applied.
