Revert Mockito to 3.11.0

Revert Mockito upgrade done in 5d919dc094 because
Byte Buddy transitive upgrade from 1.11.1 to 1.11.3 seems to break Mockk tests
with java.security.AccessControlException related errors, so probably
better to wait Mockito using Byte buddy 1.11.5+ which seems to refine
this area, see https://github.com/raphw/byte-buddy/releases/tag/byte-buddy-1.11.5.
