Can we replace #graphql comments with /* GraphQL */?

[tomtuv]

It would be great if the Skeleton template used /* GraphQL */ comments instead of #graphql, as the latter does not support formatting with Prettier (see prettier/prettier#16124).

Also, I’m not sure about the purpose of as const. It seems to break GraphQL Validation in VS Code. I removed it, and the codegen still works.

Thanks!
