documentVariableSuffix doesn't work with client preset

### Which packages are impacted by your issue?

@graphql-codegen/client-preset

### Describe the bug

`documentVariableSuffix` is not respected in the `graphql.ts`, but it is in the `gql.ts`.

I believe this is because `documentVariableSuffix` is not part of the [forwarded config](https://github.com/dotansimha/graphql-code-generator/blob/master/packages/presets/client/src/index.ts#L121-L139) for `graphql.ts`.

### Your Example Website or App

https://codesandbox.io/p/devbox/priceless-water-5p9m3h?workspaceId=ws_Gkwk4Jh3EcjEfvkuEJQn9z

### Steps to Reproduce the Bug or Issue

1. generate the files with the configuration in the codesandbox
2. there is no suffix in `gql/gql.ts`, but there is `Document` in the `gql/graphql.ts`
3. remove `documentVariableSuffix`
4. both `gql/gql.ts` and `gql/graphql.ts` has the `Document` suffix

### Expected behavior

For both `gql/gql.ts` and `gql/graphql.ts` to respect the `documentVariableSuffix`.
