[DOP-26758] Include .jar files into worker image

[dolfinus]

Change Summary

Added script which creates empty Spark session with all Maven packages included. Spark download these images into /root/.ivy2 folder, so they can be reused later. This avoids downloading packages from Maven during transfer runs.

Image size increased 933Mb -> 1.67Gb.
This is done only during release image build, because this step is slow, and Github Actions cache size for test images is limited.
