Docstring section Yield type doesn't hyperlink in napoleon

Describe the bug

Not sure if this is a new bug or a regression, see #8004. I'm reporting this bug as specific to the Yield docstring section of the sphinx.ext.napoleon extension for Google style docstrings, (perhaps #10134 is also related but it seems NumPy specific.)

So whatever the relevant configurations of napoleon or autodoc you use -I tried this with every combination I could think of- it seems the type of the Yield docstring section is never hyperlinked.

How to Reproduce

A minimal conf.py (I think it's better in this case to include all the relevant configurations with explicit values):

import os
import sys

sys.path.insert(0, os.path.abspath(os.path.join('..', '..', 'src')))

extensions = [
    'sphinx.ext.autodoc',
    'sphinx.ext.napoleon',
    'sphinx.ext.intersphinx',
]

templates_path = ['_templates']
exclude_patterns = []

html_theme = 'alabaster'
html_static_path = ['_static']

toc_object_entries = False
add_module_names = False
add_function_parentheses = True
smartquotes = False

intersphinx_mapping = {'python': ('https://docs.python.org/3', None)}

autodoc_typehints_format = 'short'
autodoc_typehints_description_target = 'all'
autodoc_preserve_defaults = True
autodoc_class_signature = 'mixed'
autodoc_docstring_signature = False

napoleon_google_docstring = True
napoleon_numpy_docstring = False
napoleon_include_init_with_doc = False
napoleon_include_private_with_doc = True
napoleon_include_special_with_doc = True
napoleon_use_admonition_for_examples = True
napoleon_use_admonition_for_notes = True
napoleon_use_admonition_for_references = False
napoleon_use_ivar = True
napoleon_use_keyword = True
napoleon_use_param = True
napoleon_use_rtype = True
napoleon_preprocess_types = False
napoleon_type_aliases = None
napoleon_attr_annotations = False

A simple example module my_package.my_module.py

from typing import Iterator


class MyClass:

    def test_method(self, my_arg) -> Iterator[int]:
        """Test docstring

        Args:
            my_arg (int): text.
        Yields:
            Iterator[int]: text
        """
        yield 1

A minimal my.rst

.. module:: my_package.my_module

    .. autoclass:: MyClass

'sphinx.ext.intersphinx']

Reproduce the issue with the provided conf.py, my_package.my_module.py, and my.rst using autodoc and napoleon. Start by tracing how the Google-style Yields section processes Iterator[int], then add a regression test that verifies the yield type is hyperlinked in the generated documentation.
