    [SPARK-34060][SQL][FOLLOWUP] Preserve serializability of canonicalized CatalogTable
    
    ### What changes were proposed in this pull request?
    Replace `toMap` by `map(identity).toMap` while getting canonicalized representation of `CatalogTable`. `CatalogTable` became not serializable after https://github.com/apache/spark/pull/31112 due to usage of `filterKeys`. The workaround was taken from https://github.com/scala/bug/issues/7005.
    
    ### Why are the changes needed?
    This prevents the errors like:
    ```
    [info]   org.apache.spark.SparkException: Job aborted due to stage failure: Task not serializable: java.io.NotSerializableException: scala.collection.immutable.MapLike$$anon$1
    [info]   Cause: java.io.NotSerializableException: scala.collection.immutable.MapLike$$anon$1
    ```
    
    ### Does this PR introduce _any_ user-facing change?
    Should not.
    
    ### How was this patch tested?
    By running the test suite affected by https://github.com/apache/spark/pull/31112:
    ```
    $ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableDropPartitionSuite"
    ```
    
    Closes #31197 from MaxGekk/fix-caching-hive-table-2-followup.
