Every openbao PR lands on area/uncategorized, because the labeler has no
scope entry for it and there would be no label to apply if it did. #4168
and #4177 are both sitting on the fallback right now.
labels.yml sets the bar for a new area at three open issues on the topic,
and openbao is at three: #2787, #2483 and #2793. It also follows the
shape already used for a single shipped component, next to area/kamaji,
area/keycloak and area/cilium.
Maps the plain `openbao` scope and `openbao-central` alongside it, since
the platform instance lives in its own package and gets its own scope.
