Make Docker image smaller

[florianm]

Problem

The Docker image contains texlive-full which makes it 6GB, 15-20 mins build time on GHA, 10 mins deploy time. The Annual report requires texlive-minimal plus a range of extra packages. The lazy way was to install texlive-full.

Feature

Reduce the installed texlive size by choosing a smaller base installation (texlive-minimal?) plus only the needed extra packages, and skip installation or delete latex docs. Doing so will be painful and time intensive, but speed up deployment cycles.

Minimal docker image: https://github.com/alchem0x2A/texlive-docker-minimal/blob/develop/Dockerfile SDIS image has tlmgr to install additional packages

See https://packages.debian.org/sid/texlive-... for what CTAN packages are included in each Debian package.

Excluded the following packages from texlive-full and ARAR still builds:

Meta-packages:

texlive-pstricks texinfo texlive-bibtex-extra texlive-extra-utils texlive-latex-extra texlive-fonts-extra texlive-fonts-extra-links

Functionality:

texlive-metapost texlive-font-utils texlive-binaries texlive-formats-extra texlive-games texlive-humanities texlive-music texlive-pictures texlive-publishers texlive-science

Languages:

texlive-lang-european texlive-lang-* (anything not English)

Any Docs

Docker image is now 1GB (down from 6GB) and builds in under 6 mins and deploys in under 1 min, down from 15min build / 10 min deploy.

v5.1.* has a smaller image (2.7GB) using a subset of texlive metapackages.
