[FEAT]: Export schema.graphql and schema.json directly

[bluwy]

Describe the need

It'd be nice to be able to import @octokit/graphql-schema/schema.graphql and @octokit/graphql-schema/schema.json, which should mean adding this to the package.json:

{
  "exports": {
    "./schema.graphql": "./schema.graphql",
    "./schema.json": "./schema.json"
  }
}

This would allow to reference the file directly for @graphql-codegen/cli:

import type { CodegenConfig } from "@graphql-codegen/cli";

const config: CodegenConfig = {
  schema: import.meta.resolve("@octokit/graphql-schema/schema.graphql"),
};

export default config;
