Add remaining field types to the full example or add documentation

[AndersBennedsgaard]

Describe the bug

Since the field types aren't documented anywhere (including the parameters they expect), it is impossible to figure out how to work with node fields.
The https://github.com/Cognigy/Extensions/blob/master/docs/example/src/nodes/fullExample.ts is supposed to be a full example, covering all the different fields types, parameters, etc. so I think this should be improved.

To Reproduce

Try to use field type condition, rule, and others. See that no examples are given and fail.
Try to use parameters for all different types, and fail because it isn't documented.

Expected behavior

Documentation on all field types and parameters, or make it part of fullExample.ts.
