Fix symbolic link in Dockerfile_java_cli

[viktoriia-fomina]

Description

Now Java CLI image is published on GitHub Packages on every push to the main branch. Current Dockerfile_java_cli creates incorrect symbolic link. The link is expected to refer to UTBot CLI but it does not.

To Reproduce

Steps to reproduce the behavior:

1. Download Java CLI docker image
2. Use Java CLI image to run its container
3. Check for symbolic links and see that it does not refer to CLI .jar

Expected behavior

Dockerfile_java_cli creates symbolic link that refers on Java CLI.

Actual behavior

Dockerfile_java_cli creates link that does not refer on Java CLI.
