Update old URL in README.rst to avoid need for redirect (#28510)

[trivial, not reviewed]

Found this outdated URL while debugging Google search console messages
while snapshotting release docs today. It hasn't been broken due to our
server-side redirects, but it seems preferable to avoid the need for the
redirect.
