Creation of a GitHub action to build the debian package after changes in this repository

[jredrejo]

In order to test changes in the repository, whenever a push is done we should trigger a package build.
To do it, we first need to recover a kolibri tar file, leave it in the build_src directory of this repository and call the kolibri.deb target from this repostory Makefile

This is a possible yaml file that's not working yet because the step of fetching a tar kolibri file has to be correctly implemented:

name: Test creation of deb package after code changes

on:
  push:
    branches:
    - develop
    - 'release-v**'
  pull_request:
    branches:
    - develop
    - 'release-v**'
  workflow_dispatch:

  workflow_call:
    outputs:
        deb-file-name:
          description: "DEB file name"
          value: ${{ jobs.build_deb.outputs.deb-file-name }}

  build_deb:
    name: Build DEB file

I would suggest copying the version I implemented here: https://github.com/learningequality/kolibri-installer-android/blob/develop/.github/workflows/pr_build.yml (and reuse the reusable debian build workflow in this repository).
