Subject: [PATCH 1/2] Fix duplicate maven-jar-plugin declaration in
 clickhouse-jdbc-all

Maven 3.10 rejects a plugin declared twice in one POM (3.9 only warned),
so every build of v0.11.0 now fails while reading the POMs. Merge the two
maven-jar-plugin declarations into one; the version now comes from
pluginManagement (3.4.2), as on main.

Only the packages/clickhouse-jdbc-all/pom.xml part of the original commit
is taken. The root pom.xml part moves the default-jar manifest
configuration out of the profiles, which is not needed for this fix.

(cherry picked from commit 91017eb5f43e16dfbce11c52a69f2cf94819ed96)

Subject: [PATCH 2/2] Fix duplicate jackson-databind declaration in
 examples/client-v2

Maven 3.10 rejects a dependency declared twice in one POM, so the
"Compile examples" CI step fails on v0.11.0. Keep one jackson-databind
dependency with the default (compile) scope, as on main.

Conflict: the version is 2.18.11 on main and 2.18.10 on v0.11.0. Kept
the branch value; the bump is part of the #3233 backport.

(cherry picked from commit 2b635d123ae1609d4f7227aaec72a656951ef23a)
