### Why are the changes needed?

Bug fix.

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

No.

### How was this patch tested?

Ran ThriftServer, connect to it and execute `CREATE TABLE mytbl2(a int) OPTIONS(url="jdbc:mysql//example.com:3306", driver="com.mysql.jdbc.Driver", dbtable="test_tbl", user="test_usr", password="abcde");` with `spark.sql.redaction.string.regex=((?i)(?<=password=))(".*")|('.*')`
Then, confirmed UI.
