This PR update the tests suite to wait for Vercel CLI tarball and then use that tarball to run E2E tests.
This is valuable because it will package all the packages in this monorepo to make the tests follow more closely what will happen in production once merged.
Since the current "Find Changes" step takes about 2 minutes, we run that first (it happens concurrently with the tarball preparation). Then once we complete "Find Changes" we wait for the tarball but it will likely be ready by that point since it also takes about 2 minutes. After both of those steps, the E2E tests continue as usual but with the `VERCEL_CLI_VERSION` set to the tarball.

Adds a new Builder for the Remix framework. This Builder has support for a few different configurations of Remix including the "just the basics" Remix server as well as the "vercel" server build target configuration. If the project does not have the `@remix-run/vercel` runtime adapter as a dependency in package.json then this Builder will implicitly add it when generating the SSR serverless function.
In a follow-up PR, we can make this Builder be used in the frameworks configuration so that it is executed when `remix` framework is selected for the project, and we can update the remix example template in this repo to no longer require the `ENABLE_FILE_SYSTEM_API` env var.
