Better documentation for the labels array of get_taxonomy_labels() function

[truongwp]

Make documentation for the labels array of get_taxonomy_labels() function better and remove @todo tag.

Hi @truongwp, thanks for the patch. I think you're on the right track, though it's a bit misleading to document the labels as first-level properties of the WP_Taxonomy object, which they really aren't.

So rather than document $tax, I think the most straightforward way to do it would be to document all of the labels in the @return notation instead.

Hi @DrewAPicture,

I had a bit confusion here. I will update the patch.

Thank you.
