Wrong error message when referring a uri with file:// rather than file:/// or file://c/

When defining a workflow, if there is a reference to an external uri, within a function definition operation, using file scheme with two / rather than three /, following error is printed "Unable to define a package name for function named 'xxxx', please consider using a different strategy defined in the kogito.sw.operationIdStrategy property" when the problem is that the URI is not consider valid by Java URI class
Need to review if file:// is a valid uri
Conclusion:
file:// is not a valid uri, updating error message
