KARAF-7829 Override org.slf4j to 2.0.12

[PeterSuna]

Override transitive dependency version for org.slf4j from 1.7.32 and 1.7.35 to 2.0.12 as defined in Karaf BOM project.

This issue arose after bumping slf4j to 2.0.12 in this commit:
03354d2#diff-9c5fb3d1b7e3b0f54bc5c4182965c4fe1f9023d449017cece3005d3f90e8e4d8R324

However, some transitive dependencies still remain at version 1.7.32 and 1.7.35. See the mvn dependency:tree output:

This can be fixed by specifying the correct version in dependency management.

Just a note: this PR doesn't actually fix the problem described in KARAF-7829.
For Karaf client slf4j issue, it's coming of the client packaging slf4j logger/binder from slf4j 1.x. I will create another PR to upgrade the client to slf4j 2.x (using Provider instead of Binder).
