BUG: numpydoc + autosumarry broken

[larsoner]

#4611 broke rendering for me of a numpydoc + autosummary html build where the input is like:

...
    Parameters
    ----------
    data : array, shape (n_chan,)
        The data values to plot.
...

Which numpydoc turns into something like:

...
:Parameters:

    **data** : array, shape (n_chan,)
        The data values to plot.
...

On the commit in master before this (b04bfcf) I get the correct output with : between items:

On master after this PR (on commit 7459d87) the colon is gone (<span> missing in output):

I'm not sure how to fix this because I'm out of my depth, though :(

I confirm the bug with the current master, the colon removed in the html output:

-<dt><strong>problem</strong> <span class="classifier-delimiter">:</span> <span class="classifier"><a class="reference internal" href=...
+<dt><strong>problem</strong><span class="classifier"><a class="reference internal" href=...
