Update dependencies minor versions to fix build on JDK 25

[bedrin]

Update assert4j from 3.26.3 to 3.27.6
Update mockito from 5.17.0 to 5.20.0
Update byte-buddy from 1.17.5 to 1.17.8
Update jackson from 2.17.0 to 2.19.2

It converges dependencies on byte-buddy and brings the version which fully supports JDK25 and works with modelcontextprotocol/java-sdk

Motivation and Context

JDK 25 is the new LTS version of Java.
modelcontextprotocol/java-sdk build fails on JDK 25 mostly due to old version of net.bytebuddy:byte-buddy library
This PR updates all libraries which depends on net.bytebuddy:byte-buddy transitively

How Has This Been Tested?

all tests are green
