lack of devcontainer

[SamStaijen]

Current situation

Currently, this project has no .devcontainer in it's project, requiring every user to locally install all the dependencies.

Fix

This should be changed to a .devcontainer, to make sure the local installation of dependencies always matches the production version of said dependencies.
Furthermore, this reduces the needfor local installation, apart from docker and a devcontainer supporting editor (for example: vscode)
