Use HTTPS links for Google domains in docs

Since almost all Google domains support HTTPS, and it is a good practice to
use HTTPS wherever possible, thus in this patch, I changed most HTTP links
to https whose domains are known to support HTTPS well.

Modifications are generated by running these commands in src/docs directory:
