Description

Partial fix for #10281. This PR makes sure that schema URLs are not being treated as file paths when creating a watcher for --watch. This allows the common watched directory to be a nested directory, which in turn dramatically increases performance of the watcher as it doesn't have to watch all the extra directories (like node_modules).

Further comments

As I said, it's only a partial fix. This resolves the issue of schema URL being treated as a file, which forces the watcher to watch the project root. However, this still does not allow the watcher to be efficient and performant when the graphql-codegen config is located in the project root, or when watched files are in two different locations.

A proper fix would be a refactor of the watcher.ts - one that utilizes multiple watcher subscriptions per each watched path OR one that automatically specifies all directories except relevant as ignored. I'm not sure which solution would give better performance, and I'm not sure that this project will accept a PR making those changes. Please let me know if this refactor would be possible.
