test: update TestGreaterOrEqualVersion for the widened MariaDB guard

The previous test included two hypothetical "future MySQL 22.x" cases
expecting `GreaterOrEqualVersion` to return true. With the guard widened
from `major == 10` to `major >= 10` in the prior commit (to stop MariaDB
11.x being misclassified as "MySQL >= 8.0.23"), those cases now correctly
return false — major >= 10 is treated as MariaDB territory.

Also adds an explicit MariaDB 11.4.9 vs MySQL 8.0.23 case so the issue #82
regression is caught directly by a unit test, plus a doc comment on the
test explaining the heuristic and pointing callers at
`common.HasCapability` for flavor-aware checks.
