bpo-39348: Fix code highlight for the SOCK_NONBLOCK example (GH-18018)


The previous double colon was wrongly place directly after Therefore.
Which produced a block without syntax highlighting. This fixes it
by separating the double colon from the text. As a result, sphinx now
properly highlights the python code.
