move @graphql-codegen/cli to dev dependencies

@graphql-codegen/cli and friends are super useful as tooling, but they
also depend on the world:

https://npmgraph.js.org/?q=%40shopify%2Fshopify_function

Just @graphql-codegen/cli and its transitive dependencies add 211
maintainers to your supply chain:

https://npmgraph.js.org/?q=%40graphql-codegen%2Fcli

It also creates noise re: CVE spam in a long tail of dependent packages.

As far as I can tell, there's no runtime dependency on any of these
packages -- so we can freely move them to dev dependencies.
