Fix indentation python-mode/function_docstring_numpy

[oliveira-julio]

the indentation was wrong, using only one space instead of 4.

But what about the # NOTE: Use minimum indentation, because Emacs 25+ doesn't dedent docstrings.? (I'm pretty sure I wrote that note, but I don't recall the exact details right now)

[oliveira-julio]

the indentation was not a multiple of four.
the snippet function_docstring_numpy has the correct indentation.
function_docstring is now with the same indentation.

I use Emacs 25.3.1, and the docstring is working.

Did you check with python-indent-offset set to 2 (as described in joaotavora/yasnippet#750)?

:O plot twist, function_docstring_numpy is wrong.
