Type for JsonSchema

Hey, I am not entirely sure whether this is the right place to ask this, sorry if not.

**What version of Ajv you are you using?**
8.12.0

**What problem do you want to solve?**
I want to define a schema containing multiple schema definitions.

To be specific, I need to write a validation schema for the variables possible to pass to a serverless plugin specifying that the user can pass schemas to compile before packaging to the plugin.
In the end, it would look like the following:
```typescript
{
myPlugin: {
schemas: [
schema1,
schema2
]
}
}
```

**What do you think is the correct solution to problem?**
Maybe there is already something like this, I tried
```typescript
{
type: "object",
properties: {
schemas: {
type: "array",
items: {
$ref: "http://json-schema.org/draft-07/schema"
},
},
}
```
but received the error `Error: Unsupported reference http://json-schema.org/draft-07/schema`

**Will you be able to implement it?**
No
