Translate sphinx.po #3

What this is

sphinx.po has the text of the documentation home page and the sidebar: the main headings, the "Download", "Docs by version" and "Other resources" blocks, and similar short labels. It has 114 strings.

This is the first thing every reader sees, so it is our top priority. Right now the Punjabi home page is still in English.
