(ref #91)

This reverts commit c4fa14a1.

The How To Ask Questions The Smart Way page links to some
translations, including pt-br. So how about use it instead?

Adapted the text for better readability in Italian language.
Also clarified that the URLs in "Other similar problems" and "Further reading" sections point to resources in English.

"אל תשאל בשביל לשאול" is more "don't ask for ask" than "don't ask to ask"

This commit adds an automatic dark mode for when the user’s device is
itself in dark mode.

Proofreading what I wrote back in the time, I think this is probably better
title in terms of making it less English. (I mean, grammatically).
