Bump minimum version of Bison to 2.3
Since the retirement of some older buildfarm members, the oldest Bisonthat gets regular testing is 2.3. MacOS ships that version, and willcontinue doing so for the forseeable future because of Apple's policyregarding GPLv3. While Mac users could use a package manager to installa newer version, there is no compelling reason to force them do so atthis time.Reviewed by Andres FreundDiscussion:https://www.postgresql.org/message-id/1097762.1662145681@sss.pgh.pa.us
