[PATCH iproute2] README: re-add updated information link

From: Quentin Monnet <redacted>

The "Information" link was removed from README file in commit
d7843207e6fd ("README: update location of git repositories, remove
broken info link"), because it redirected to a page that no longer
existed on the Linux Foundation wiki.

This page has just been restored, so we can add the link back again.
Since the previous link was a redirection, use the updated link instead.

Thanks to Luca Boccassi for investigating this issue, restoring and
updating the page.
