How to set $id for slices?

[pascalbreuninger]

Hey everyone,

I tried to add an ID to a slice based schema type today but wasn't able to find out how to achieve this.
Minimal required steps are:

	r := new(jsonschema.Reflector)

	schema := r.Reflect(&[]struct{}{})
	json, _ := schema.MarshalJSON()
	println(string(json))

the output is:

{
"$schema":"https://json-schema.org/draft/2020-12/schema",
"items":{"properties":{},"additionalProperties":false,"type":"object"},
"type":"array"
}

Which options do I have to add an $id field here?

Thanks in advance 🙇
