audeer.deprecated() interferes with the docs

[hagenw]

E.g. assume we have the following class definition:

@audeer.deprecated(removal_version="2.2.0")
class Repository:
    r"""Repository object.
    ...
    """

    def __init__(
        self,
        name: str,
        host: str,
        backend: str,
    ):  
        # ...

when including this in an API documentation it results in

instead of the expected

In addition, it prevents class attributes to show up in the documentation.
