The language code of [query][google.cloud.talent.v4.JobQuery.query]. For
example, "en-US". This field helps to better interpret the query.

If a value isn't specified, the query language code is automatically
detected, which may not be accurate.

Language code should be in BCP-47 format, such as "en-US" or "sr-Latn".
