fix(deps): move graphql-tag to devDeps from peerDeps (#805)

`graphql-tag` is only used in .spec files within the `typescript-react-apollo` package. Similar to `typescript-apollo-angular`, this commit moves `graphql-tag` to devDependencies so package consumers aren't required to install it to remove warning:

```
warning " > @graphql-codegen/typescript-react-apollo@4.3.0" has unmet peer dependency "graphql-tag@^2.0.0".
```
