* feat: build and distribute .deb packages
Creates .deb packages for distribution via GitHub releases and Buildkite builds for the following architectures:
* amd64
* armhf
* arm64
* fix: pkgver reference in debpackages.sh
* refactor: split deb packaging jobs and quote variables
* fix: pipeline upload for debpackages
* fix: depends_on key for debpackages
* fix: add depends_on: ~ for debpackages step
* fix: pre-artifact hook for debpackages
* fix: add .deb suffix in pre-artifact hook
* fix: variable reference in debhelper.sh
* refactor: silence wget output in debhelper.sh
* refactor: make build concurrency gate only depend_on docker builds
* refactor: make build concurrency gate also depend_on coverage build
* refactor: remove dependencies for build concurrency gate
* Optimise deploy artifacts step
authelia-scripts is not required to publish GitHub artifacts as we utilise [Hub](https://hub.github.com/), this should save ~10 seconds in this step.
* Specify release number in pipeline
* Change buildkite and github published artifacts back to gzip
* Update README.md
