Block JSON schema: Add viewScriptModule field

[t-hamano]

Related to #58203

What?

This PR adds a viewScriptModule field to the schema of block.json.

Why?

To enhance the developer experience. My understanding is that viewScriptModule is now officially published instead of viewModule.

Testing Instructions

Create a JSON file like the one below and open it in a code editor.

{
	"$schema": "https://raw.githubusercontent.com/WordPress/gutenberg/schema/block-json-view-script-module/schemas/json/block.json",
	"name": "test/test",
	"title": "Test"
}

You should see viewScriptModule reference.

Thanks for the PR!
I need to test if we are supporting arrays at this moment.

[t-hamano]

Thanks for the review! From what I've researched, it appears to support arrays.
