ad hoc client versions are confusing

While the version from client programs is rarely observed, sometimes its just used incorrectly like https://stackoverflow.com/questions/74601477/best-directory-for-data-exchange-between-php-and-mariadb-on-ubuntu to describe the server version.

As these versions are never used without the compiled server version beside it, lets just drop the client version as the updating pattern for these at best is sparadic.
