Fix display of supported series & architectures


I filed this bug on Github,, but I think that goes to the Web & Design team.

The new recommended path forward for charms is to have Launchpad charm recipes set up to build and publish those to Charmhub. The recommended path is to also use charmcraft.yaml's bases and separate builds per series, per architecture.

Unfortunately, charmhub shows the supported platform series and architecture of the most recently completed build, the one completed and uploaded last, with the highest revision.

Can we have this fixed? Doesn’t seem like an easy one to tackle.
