Don't see any issue opened for PIT test failures. I tried running the tests in my laptop, failures are happening in main branch as well, but its flaky because I could see a lot of builds passing, but somehow consistent failure in this PR

Tests with failures:
 - org.opensearch.search.DeletePitMultiNodeTests.testDeletePitWithValidAndDeletedIds
 - org.opensearch.search.DeletePitMultiNodeTests.testDeleteWhileSearch
 - org.opensearch.search.DeletePitMultiNodeTests.testDeletePitWhileNodeDrop
 - org.opensearch.search.DeletePitMultiNodeTests.testDeleteAllPits
 - org.opensearch.search.DeletePitMultiNodeTests.testDeletePit
 - org.opensearch.search.DeletePitMultiNodeTests.testtConcurrentDeletes
 - org.opensearch.search.DeletePitMultiNodeTests.testDeleteAllPitsWhileNodeDrop
 - org.opensearch.search.DeletePitMultiNodeTests.testDeletePitWithValidAndInvalidIds
 - org.opensearch.search.DeletePitMultiNodeTests.classMethod

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-5255-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 e0ddf524e705097a5e52ddbc9f7045680a38ffb2
# Push it to GitHub
git push --set-upstream origin backport/backport-5255-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-5255-to-2.x.
