Documentation pointing to the registerNetwork() overload including a
timeout argument was pointing to the version removed by commit
139a48c83c. This makes it impossible to
cherry pick 139a48c83c due to the linter
complaining about unresolvable links.
This patch fixes the documentation to point to the registerNetwork()
with argument types NetworkRequest, NetworkCallback, int, in that order.
