VERMISMATCH error should be issued based on $ZYRELEASE and not $ZVERSION
Final Release Note
No release note needed because a user will never encounter this error.
Description
Currently the VERMISMATCH error is issued in the database logic based on $ZVERSION but it should be fixed to use $ZYRELEASE instead. This is because if two successive YottaDB releases are based off the same GT.M version, their $ZVERSION would be the same (meaning they would be incorrectly treated as the same version) but their $ZYRELEASE would be different and using that should ensure they are treated as two different versions.
Draft Release Note
N/A. No release note needed since this is going to be fixed before the second release of YottaDB (which is the first release where a VERMISMATCH error is even possible between two releases of YottaDB).
