Enable OpenSSF allstar for the entire org (in addition to scorecard in the core repo)

[AkihiroSuda]

OpenSSF scorecard was enabled for the core repo in containerd/containerd#7404 but probably we don't want to maintain this for all the repos under the containerd org.

Can we enable allstar for the entire org, in addition to the scorecard in the core repo?

SGTM.. though would prefer opt in strategy.. so we don't have to remember to add opt out for new repos that do not meet the need for scoring.. either way works..
