The outdated command is just a proxy for `composer show -l`

The color coding for dependency versions is as such:

- <info>green</info>: Dependency is in the latest version and is up to date.
- <comment>yellow</comment>: Dependency has a new version available that includes backwards
  compatibility breaks according to semver, so upgrade when you can but it
  may involve work.
- <highlight>red</highlight>: Dependency has a new version that is semver-compatible and you should upgrade it.
