Umherirrender c8ec25a961 maintenance: Add missing documentation to class properties
Add doc-typehints to class properties found by the PropertyDocumentation
sniff to improve the documentation.

Once the sniff is enabled it avoids that new code is missing type
declarations. This is focused on documentation and does not change code.
