HTTPCLIENT-2319  / Updated the parseDate method to solely catch DateTimeException, streamlining error handling for date parsing and conversion. This change ensures comprehensive management of parsing issues, including those due to absent time-zone information, aligning with our documentation that the method should return null when conversion to Instant is not feasible. (#551)
