[Feature] Allow language selection at installation

[dan0v]

Is your feature request related to a problem? Please describe.
Installation in any form takes a long time on weak hardware like a Raspberry Pi. Specifically, installing using the arm32v7 docker file took over an hour on my Pi 3b+ running Nextcloud. Of this total installation time, building languages took around 16 -18 minutes per language, followed by another approximately 4 minutes initializing each language.

Describe the solution you'd like
Seeing as users will likely use only one or two languages, allow users to select languages to install (or provide different installation scripts for each language) when installing.

Hi,

I'll look into it. (sorry, but cannot promise any deadline. Probably it will take up months. Super busy lately. :/)
In the meantime you can:

• If you delete files from the translate folder the app wont translate to that language. (Dont delete the english one, it might give an error)
• you can download a precompiled release and install that one.

In both cases you will need to download the source manually and COPY it to the container and not using the git clone in the Docker file.

The latest commit should add this feature.
Usage:
npm run create-release -- --languages=fr,ro to build & zip the release from source (potentially on a strong computer and then transfer release to the server)
npm run build-prod-- --languages=fr,ro to build it from source
