Subject: [PATCH] Add now mandatory readthedocs config file

Docs builds currently fail with:

```
Problem in your project's configuration. No default configuration file found at repository's root. See https://docs.readthedocs.io/en/stable/config-file/
```

See e.g. https://readthedocs.org/projects/requests/builds/22842479/
