    [SPARK-52363][SQL][TESTS] Analyzer NameScope test for nested struct fields inside map values
    
    ### What changes were proposed in this pull request?
    This PR adds test coverage for resolving nested struct fields inside Map values which was missing in the original test suite.
    
    ### Why are the changes needed?
     The new test verifies that multi-part resolution like mapColumn['key'].nestedField works correctly, we already defined a field `col11MapWithStruct`, but we didn't test it properly.
    
    ### Does this PR introduce _any_ user-facing change?
    No
    
    ### How was this patch tested?
    Unneeded
    
    ### Was this patch authored or co-authored using generative AI tooling?
    No
    
    Closes #51059 from dengziming/SPARK-52363.
