[SPARK-36483][CORE][TESTS] Fix intermittent test failures at Netty 4.1.52+

### What changes were proposed in this pull request?

Fix an intermittent test failure due to Netty dependency version bump.
Starting from Netty 4.1.52, its AbstractChannel will throw a new `StacklessClosedChannelException` for channel closed exception.
A hardcoded list of Strings to match for channel closed exception in `RPCIntegrationSuite` was not updated, thus leading to the intermittent test failure reported in #33613

### Why are the changes needed?

Fix intermittent test failure

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

Closes #33713 from Victsm/SPARK-36378-followup.
