    ### Rationale for this change
    
    ```text
    ruby/red-arrow/test/test-buffer.rb:26: warning: ObjectSpace._id2ref is 
deprecated
    ```
    
    ```text

and use Ractor#value instead. This method will be removed after the end of Aug 
2025
    ```
    
    ### What changes are included in this PR?
    
    * Use `ObjectSpace::WeakMap` instead of `ObjectSapce._id2ref`
    * Use `Ractor#value` instead of `Ractor#take`
    
    ### Are these changes tested?

    No.
