UncheckedJSONSchemaType ['type'] field does not support 'array', 'object', and 'null' in an array

**What version of Ajv are you using? Does the issue happen if you use the latest version?**
8.17.1, Yes

Here is a link to the documentation:
https://json-schema.org/understanding-json-schema/reference/type

The syntax I have given is valid and supported by ajv and works. Error only in JSONSchemaType:

```typescript
import type { JSONSchemaType } from 'ajv';

type NullInTypeFieldArray = { someField: number | null };
const nullInTypeFieldArraySchema: JSONSchemaType = {
type: 'object',
required: ['someField'],
properties: {
someField: { type: ['number', 'null'] },
},
};

type ObjectInTypeFieldArray = { someField: { anotherField: number } | null };
const objectInTypeFieldArraySchema: JSONSchemaType = {
type: 'object',
required: ['someField'],
properties: {
someField: {
type: ['object', 'null'],
properties: {
anotherField: { type: 'number' },
},
},
},
};

type ArrayInTypeFieldAArray = { someField: string[] | null };
const schemaWithArrayInType: JSONSchemaType = {
type: 'object',
required: ['someField'],
properties: {
someField: {
type: ['array', 'null'],
items: { type: 'string' },
},
},
};
```

**Validation result, data AFTER validation, error messages**
Very long typescript type check error:
