feature: Support full function type signatures

[multimeric]

Is your feature request related to a problem? Please describe.

I want to display the full type signature of my functions, because I feel that this better summarises how to use them.

Describe the solution you'd like

A function with signature like this:

def subjects(self, predicate: URIRef, object: URIRef) -> Iterable[UriNode]: ...

Should result in a code block with all the type annotations included, e.g.

subjects(self, predicate: URIRef, object: URIRef) -> Iterable[UriNode]

Whereas currently it lacks this:

subject(predicate, object)

There is an option for this in the code, but it seems that the CLI does not expose the ability to specify options.

For a project I was customizing the markdown generation a bit with programmatic usage of griffe2md. Roughly something like:

import griffe
from griffe2md.rendering import default_config
from griffe2md.main import render_object_docs

config = dict(default_config)
config["show_signature_annotations"] = True

mod = griffe.load("my_package", docstring_parser="google")
output = render_object_docs(mod, config)
# write output string to a file

In case this helps
