Azion builder for Next.js apps

/**
 * This patch will replace the createSnapshot function in the
 * server/app-render/async-local-storage.js file to an empty string.
 * This is necessary because the createSnapshot function is causing I/O issues for
 * ISR/SSG revalidation in Cloudflare Workers.
 * This is because by default it will use AsyncLocalStorage.snapshot() and it will
 * bind everything to the initial request context.
 * The downsides is that use cache function will have access to the full request
 * ALS context from next (i.e. cookies, headers ...)
 * TODO: Find a better fix for this issue.
