[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.
