settings: Fix JSON schema for ExtensionCapabilityContent (#39478)

This PR fixes the JSON schema for the `ExtensionCapabilityContent`.

Having the nested structs in the variants caused the `kind` property to
not be generated properly. Inlining the fields into the variants fixes
this.

Release Notes:

- N/A
