array_join: Expression Fuzzer throws exception for the json type

[xiaodouchen]

Description

When I add support for the unknown type to array_join(), running the CI/CD tests results in the error "Presto query failed: 13 No default Hive type provided for unsupported Hive type: json" (More detailed info in the following picture). After searching through existing issues, I found that this is a known issue(#9767 and #12286).

Hi @xiaodouchen - Can you post the CI run where this is failing or paste the logs (CI run being more preferrable) rather than a screenshot ?

Noticed this while adding the skip list to stabalize the fuzzer. Didn't look to deep into it but likely a json/hive in-congruency affecting json functions. Will try to take a deeper dive on this particular issue
