For reference, the chromium-browser package in focal and upwards is a simple wrapper that installs the chromium snap, and it has a custom apport hook that attaches some of this information. The names of the keys there are:
- Snap.Changes
- Snap.Connections
- Snap.Info.chromium
- Snap.Info.core
- Snap.Info.core18 (this needs to be updated because it is currently hardcoded in the hook, but the snap has since been rebased on core20)
- Snap.Info.gtk-common-themes

See bug #1958810 for an example.
There isn't any tooling that expects these specific names though, so as far as I'm concerned they can be changed.
