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
