Fix warning about undefined label in docs
Error during `make html`:
wagtail/docs/releases/1.7.rst:25: WARNING: undefined label: jpeg_image_quality
Signal receivers must accept `**kwargs`, otherwise one runs into this:
```
File "/lib/python3.8/site-packages/django/dispatch/dispatcher.py", line 94, in connect
raise ValueError("Signal receivers must accept keyword arguments (**kwargs).")
ValueError: Signal receivers must accept keyword arguments (**kwargs).
```
... when using the ``WAGTAILIMAGES_IMAGE_MODEL``/``WAGTAILDOCS_DOCUMENT_MODEL`` settings.
We can't really support this as we add new fields and methods to these base classes which all images/documents must support. If we did want to support swapping out the models entirely, every addition we make to the base models could be a breaking change.
Fixes #1158
Add config options WAGTAILDOCS_CONTENT_TYPES and WAGTAILDOCS_INLINE_CONTENT_TYPES to determine the Content-Type and Content-Disposition headers returned for documents when using the Django serve view, and default to application/pdf being served inline.
