Fix Durable Object Migrator

[austinm911]

Ran into an error where the durable object function was not parsing the migrations.json file produced

export class DrizzleDurableObject extends DurableObject {
	storage: DurableObjectStorage
	db: DrizzleSqliteDODatabase<typeof schema>

	constructor(ctx: DurableObjectState, env: Env) {
		super(ctx, env)
		this.storage = ctx.storage
		this.db = drizzle(this.storage, { logger: true })
		ctx.blockConcurrencyWhile(async () => {
			console.log('Migrations object:', JSON.stringify(migrations, null, 2))

			await migrate(this.db, migrations)
		})
	}
}
