3.3.2 causing reference target not found errors for named tuples

[selimt]

We recently started getting CI failures and the cause was the 3.3.2 release of autoapi.

Although a class was imported and declared in the rst file, we started getting the following error:

sphinx.errors.SphinxWarning: /app/docstring of catalog.CatalogClient.get_taggables_unique_values:1:py:class reference target not found: catalog.schemas.UniqueValue

UniqueValue is a named tuple is declared as:

UniqueValue = collections.namedtuple(
    "UniqueValue", ("value", "count")
)

And is included in the documentation as:

.. autoapimodule:: catalog.schemas
    :members:  [redacted], UniqueValue

Going back to release 3.3.1 resolves the issue.

Thanks in advance.
