docker pull buildpack-deps:curl downloads ancient version

[TimWolla]

On two different systems when pulling buildpack-deps:curl I'm receiving a version from 18 months ago:

My local Ubuntu 20.04 machine:

$ docker images |grep buildpack-deps
buildpack-deps                                                                                         buster          6ea119635dd5   8 months ago    802MB

I wonder if it's the metadata that is wrong because that index is from 13 days ago:

See docker-library/httpd#266 (comment), docker-library/rabbitmq#686 (comment), and https://github.com/docker-library/meta-scripts/blob/d7eadbdecf7a6e7b4e04304f042f232ca5581a99/meta.jq#L170

wow is that terrible UX. Thank you. Should the timestamp perhaps be the timestamp of the base image or the latest git commit, whichever is later, instead? That would at least ensure that the image show up as reasonably recent whenever the base image is rebuilt.
