Conflict with directives `seealso`, `deprecated`, ...

[soxofaan]

Minimal reproduction example:

def hello() -> str:
    """
    .. seealso:: more info at <https://example.com>`_.
    """
    return "Hello, world!"

This triggers this warning during build:

.../helloworld.py:docstring of helloworld.hello:3: WARNING: Explicit markup ends without a blank line; unexpected unindent.

(using sphinx==7.4.1, sphinx_autodoc_typehints==2.2.2)

when running with -vv, I see this output is generated:

[autodoc] output:

.. py:module:: helloworld


.. py:function:: hello()
   :module: helloworld


   .. seealso:: more info at <https://example.com>`_.
   :rtype: :sphinx_autodoc_typehints_type:`\:py\:class\:\`str\``

rst apparently expects a new line between the seealso directive and the rtype field

Workaround is to manually add a newline, like so:

    """
    .. seealso:: more info at <https://example.com>`_.

    """

but that is of course not ideal as it is very tempting to clean up that trailing whitespace if you don't know what is for

comparable use case that triggers warning for same reason:

def greetings() -> str:
    """
    .. deprecated:: 1.2.3
       Use :func:`hello` instead.
    """
    return "Hello, world!"

Thanks for the report @soxofaan, #468 should fix it.

awesone, I see you also released 2.2.3 including that fix 👍

I can confirm that this eliminates a bunch of warnings in our build
