feat(DX): shortcut to Array Schema Validator

[mtt-artis]

Hi 👋

This is an initial attempt to address issues #402 and #921.

Changes Introduced:

• Array Type Aliases: Appended [] to the body and response schema identifiers to represent an array type alias (à la arktype). This transformation converts the schema into t.Array(t.Ref(MySchema)).

• Prefilled $id Field: Automatically prefilled the $id field to allow seamless referencing within the API documentation.

Here's an example

const app = new Elysia()
	.model({
		number: t.Number()
	})
	.post('/', ({ body }) => body, {
		response: 'number[]',
		body: 'number[]',
	})

Feel free to suggest or make any modifications as needed!
