🛠 Fix Dockerfile (#478)

* Fix Dockerfile

1. Install `nodejs npm ruby` (first two required by prettier hook,
last one required by markdownlint)
2. Readd `./requirements/dev.txt` with appropriate packages needed for
development

* Address codacy complaints

* Disable pip cache in Dockerfile for smaller Images

* Pin versions to the ones used by pre-commit
