fix: improve def command

[kobenguyent]

Motivation/Description of the PR

• improve def command, so when we have multiple custom helpers, WithTranslation<Methods> would be enough instead of WithTranslation<GraphQL>, WithTranslation<CustomGraphQL>

/// <reference types='codeceptjs' />
type steps_file = typeof import('./steps_file');
type CustomGraphQL = import('./CustomGraphQL');

declare namespace CodeceptJS {
  interface SupportObject { I: I, current: any }
  interface Methods extends GraphQL, CustomGraphQL {}
  interface I extends ReturnType<steps_file>, WithTranslation<Methods> {}
  namespace Translation {
    interface Actions {}
  }
}
