[3.10] gh-91838: Use HTTPS links in docs for resources which redirect to HTTPS (GH-95527) (GH-95644)

If an HTTP link is redirected to a same looking HTTPS link, the latter can
be used directly without changes in readability and behavior.
It protects from a men-in-the-middle attack.

This change does not affect Python examples..
(cherry picked from commit f79547a4)
