(low prio) make dev-requirement does not work out of box

[MarekNovakACRIOS]

• [x] The issue is present in the latest release.
• [x] I have searched the issues of this repository and believe that this is not a duplicate.

What happened?

I used ubuntu 18.04 vanila docker to build chirpstack-network-server and when running make dev-requirements (after installing make itself ....), it breaks because golang is missing. Maybe adding apt install golang into the dev-requirements target should be considered to make this work out of box. When using ubuntu 18.04, it is even more complicated to make it work.... so maybe only 20.04+ can be marked as supported.

What did you expect?

I expected, that make dev-requirements handles all the requirements for building the repository.

Steps to reproduce this issue

Steps:

1. docker run -it --network="host" -v "$(pwd):/workdir" ubuntu:20.04
2. once you are in the docker console, clone git repository of chirpstack-network-server
3. apt install make
4. enter the cloned folder and type make dev-requirements

Could you share your log output?

/bin/sh: 1: go: not found
/bin/sh: 1: go: not found
go install golang.org/x/lint/golint

Your Environment

docker run -it --network="host" -v "$(pwd):/workdir" ubuntu:20.04

The recommended way is to use Docker Compose, the steps are explained here: https://www.chirpstack.io/network-server/community/source/. That environment uses a Dockerfile which comes with all the requirements included.
