Issue description

When GDScript generates documentation for the getter / setter of custom class properties it doesn't mention the name of the existing class functions if used by the getter / setter, as seen below:

This is not inline with the way built-in class documentation is, as seen below:

I'm not too sure, but I'm inclined to believe that this was designed on purpose with the idea in mind that the getter / setter will be a code block (i.e. having no method name), but this fails to account for the use of existing class functions. Meaning that if I wanted to know the name of the getter / setter method I'd have to search for them in the source directly, which is not preferred.

Steps to reproduce

1. Open example project
2. Open documentation for "CustomClass"
3. No mention of getter / setter method name for custom_property_a property
