Adding pluckConfig

[Yamashou]

Is your feature request related to a problem? Please describe.

I use GraphQL Code Generator for my React projects. I am using pluckConfig in the configuration of that project. I would like to separate the target GraphQL API for each gqlMagicComment. However, since I can only separate them per file, the editor does not recognize the Query of different APIs inside the same file.

Describe the solution you'd like

Add pluckConfig to allow Schema to be set for each gqlMagicComment.

Describe alternatives you've considered

• Split a file for each Query of the target Schema
• Tolerate editor errors and give up completion

Additional context

I am using this extension.
