Migrate to the new way to do imports
Context
With the migration to the new flathub infra, It's not possible to import the runtime in the traditional way through https://flathub.org/builds/#/builders/7 -> import
Description
12:22 <@alexlarsson> and, that will not have the import thing, you need to switch to uploading to the flat-manager api
12:23 — jjardon starts another import https://flathub.org/builds/#/builders/7/builds/80
12:23 <jjardon> alexlarsson: ok, is there more info about that somewhere? I will open an issue in our bug tracker
12:24 <@alexlarsson> Not really. There is some basic docs at https://github.com/flatpak/flat-manager/blob/master/README.md
12:24 <@alexlarsson> you could probably follow that to set up a local flat-manager to test against
12:25 <@alexlarsson> Then we'll hand you a token that lest you upload in the org.freedesktop.Sdk namespace
