better CI for json plugin #572

Forcing -DUSE_JSON=EMBEDDED is not ideal. We should do like for all other libraries, include it in some test images (the all images) and not others (the mini images) so that we test both the SYSTEM and EMBEDDED situations.
If we want to switch the plugin from OFF by default to "${BUILD_UNSTABLE}", there are a few things we should do:
- We should create new test images with these new dependencies (v4). And since Ubuntu Focal is becoming unsupported, I would also switch to Jammy as the oldest version we support.
- This also means this is a new dependency that should be documented.
- We should make a Checklist of what to do when introducing a new plugin.
- We'll have to package this new plugin in all our packaging (binary, spack, etc.)
I propose to make an issue about this and enable the plugin as an unstable one in the next feature release, but keep it as a disabled preview for this release so that we don't delay it too much.
