1.8.2 breaks empty classes with multiline comments

[tannewt]

Hi hi, thanks for the improvements to autoapi! It looks like 1.8.2 broke our doc build: https://github.com/adafruit/circuitpython/runs/3167416491

The cause looks to be this input stub:

class RoleError(BluetoothError):
    """Raised when a resource is used as the mismatched role.

    For example, if a local CCCD is attempted to be set but they can
    only be set when remote."""

    ...

The generated rst is:

.. py:exception:: RoleError

   Bases: :py:obj:`BluetoothError`

   Raised when a resource is used as the mismatched role.

       For example, if a local CCCD is attempted to be set but they can
       only be set when remote.
   Initialize self.  See help(type(self)) for accurate signature.

The error is:

/home/tannewt/repos/circuitpython/shared-bindings/_bleio/index.rst:49:Block quote ends without a blank line; unexpected unindent.

Sorry about that. I've just done a release of v1.8.3 which fixed the problem. It works against circuitpython locally for me.

Thank you!
