Unmute MixedClusterClientYamlTestSuiteIT test {p0=mtermvectors/10_bas… …ic/Tests catching other exceptions per item}

[chrisparrinello]

Fixes #122414

I ran the test in a shell loop about 130 times with the failing test seed and had no reproduction of the error:

#!/usr/bin/env zsh

while true; do
  ((attempt++))
  echo "Attempt $attempt: running: foo"
  echo "\n" >> rest-api-spec/src/yamlRestTest/resources/rest-api-spec/test/mtermvectors/10_basic.yml
  ./gradlew ":qa:mixed-cluster:v8.19.0#mixedClusterTest" -Dtests.class="org.elasticsearch.backwards.MixedClusterClientYamlTestSuiteIT" -Dtests.method="test {p0=mtermvectors/10_basic/Tests catching other exceptions per item}" -Dtests.seed=BD4737A25262CDC3 -Dtests.bwc=true -Dtests.locale=zh-Hans-MO -Dtests.timezone=Etc/GMT-2
  rc=$?

  if (( rc != 0 )); then
    echo "Command returned non-zero exit code $rc on attempt $attempt"
    exit $rc
  fi
  sleep 1
done

I had to modify the underlying Yaml file to ensure the test reran each iteration, hence the echo "\n" statement.
