SC schema still has "adapter" defaulting to "legacy"

No idea what the “adapter” property does, but it seems like this snippet could use updating in snapcraft.json given much newer snapd:

                    "adapter": {
                        "$comment": "Full should be the default, but it requires command-chain which isn't available in snapd until 2.36, which isn't yet stable. Until 2.36 is generally available, continue with legacy as the default.",
                        "type": "string",
                        "description": "What kind of wrapper to generate for the given command",
                        "enum": [
                        "default": "legacy"
