Add git to pandoc images

[me-kell]

AFAICS the pandoc images (pandoc/latex etc.) have not git installed.

On the other side I see in the alpine/Dokerfile that git is added with apk:

dockerfiles/alpine/Dockerfile

Lines 7 to 21 in 61b1fbf

	RUN apk --no-cache add \
	alpine-sdk \
	bash \
	ca-certificates \
	cabal \
	fakeroot \
	ghc \
	git \
	gmp-dev \
	libffi \
	libffi-dev \
	lua$lua_version-dev \
	pkgconfig \
	yaml \
	zlib-dev

Do I miss some point or git is actually not installed in pandoc/latex?

We're using a multi-step process: first we create a "builder" container that contains all the tools required to build pandoc from source. After that's done we create a fresh container that has only a very minimal set of tools installed. Each FROM line creates a new container, and for the shipped containers we just copy the artifacts created in the build containers.

@tarleb Oh. I see. Thanks for the explanation.

@me-kell FTR the dalibo/pandocker image is based on pandoc/extra and it contains git
