Settings documentation exposes local path

[sveetch]

Describe the bug

As it can be seen here: https://diskette.readthedocs.io/en/latest/settings.html#diskette.settings.DISKETTE_DUMP_PATH

Autodoc resolve the path and will display it as the default setting value, which is not very nice to do.

Environment

Describe your environment:

• Plateform: Window/IOS/Linux distribution
• Python version: Any
• Diskette version: Any

Expected behavior

I don't really know yet how to solve this but a local path should not be exposed since it can trouble developers and may be a potential security concern, even it will always be about the RTD build environment.
