required within a property is ignored by json2ts in a JSON Schema version draft-03

[mardukbp]

Given (an excerpt of) the Xray JSON Schema:

{
    "type": "object",
    "$schema": "http:https://json-schema.org/draft-03/schema",
    "required": false,
    "properties": {
        "testExecutionKey": {
            "type": "string",
            "required": false
        },
        "tests": {
            "type": "array",
            "required": true,
            "items": {
                "type": "object",
                "required": false,
                "properties": {
                    "status": {
                        "type": "string",
                        "required": true
                    },
                    "testKey": {
                        "type": "string",
                        "required": true
                    }
                }
            }
        }
    }
}

executing

json2ts xray.json > xray.d.ts

produces

export interface Example {
  testExecutionKey?: string;
  tests?: {
    status?: string;
    testKey?: string;
    [k: string]: unknown;
  }[];
  [k: string]: unknown;
}

Whereas converting the following schema:

{
    "type": "object",
    "$schema": "http:https://json-schema.org/draft-03/schema",
    "required": ["tests"],
    "properties": {
        "testExecutionKey": {
            "type": "string"
        },
        "tests": {
            "type": "array",
            "items": {
                "type": "object",
                "required": ["status", "testKey"],
                "properties": {
                    "status": {
                        "type": "string"
                    },
                    "testKey": {
                        "type": "string"
                    }
                }
            }
        }
    }
}

produces the expected result:

export interface Example {
  testExecutionKey?: string;
  tests: {
    status: string;
    testKey: string;
    [k: string]: unknown;
  }[];
  [k: string]: unknown;
}

This isn't a valid JSONSchema. required must be an array of keys that are required. required: true isn't a thing.

See https://json-schema.org/draft/2020-12/json-schema-validation.html#rfc.section.6.5.3

6.5.3. required

The value of this keyword MUST be an array. Elements of this array, if any, MUST be strings, and MUST be unique.
An object instance is valid against this keyword if every item in the array is the name of a property in the instance.
Omitting this keyword has the same behavior as an empty array.
