Fix published docs

Change I90d064e63baa5f067f38a881eb9a556dfb435e97 contained a few typos
which broke the PDF and "Report a bug" icons on
https://docs.openstack.org/horizon/latest/ .

Fix the typos.

Change pygments_style to 'native' since old theme version always used
'native' and the theme now respects the setting and using 'sphinx' can
lead to some strange rendering.
