Load worker jars regardless of the user have lib folder or not in their function

[amamounelsayed]

There is one edge case that we do not load the java worker jars in case there is no lib folder in the java functions.

Impact

• if the user has dependencies
• And depend on the java worker only for any of the jars they need.
• And they did not have any lib jars folder in their functions.

This will fail loading their jars as we shaded the worker now and in this case we did not load the worker jars.
