Fix test on incompatible client versions (#56234)

The incomatible client version test is changed to:
- iterate on all versions prior to the allowed one_s;
- format the exception message just as the server does it.

The defect stemed from the fact that the clients will not send a
version's qualifier, but just major.minor.revision, so the raised
error/exception_message won't contain it, while the test expected it.

(cherry picked from commit 4a81c8f)
