How to write api docs (contributing) is outdated

This reflects how we used to document not how we currently do it https://qcodes.github.io/Qcodes//community/contributing.html#documenting-qcodes

It should be updated

Start with the linked contributing.html#documenting-qcodes section and compare its instructions with the current API documentation process. Update the section so it describes the current workflow rather than the former one. Done means the contributing guidance accurately reflects how QCoDeS is currently documented.
