When Installing Composer Packages from Git `git` is needed.

[simeon-smith]

Is your feature request related to a problem? Please describe.

When the php-dev-craft docker container was setup it was failing because I had a composer package that was being sourced from GitHub.

Describe the solution you would like

Adding git to the apt-get install -y portion of the php-dev-craft Dockerfile resolves this.

Describe alternatives you have considered

I don't think there's an alternative since composer requires git to install from a git repo.

Yep, that makes sense -- and if you're using git-based repos, you should add that to your php-dev-craft
