Draft: Make pathGoPkg Configurable by the User instead of being fixed

What does this MR do?

This MR is mainly for the GoSec analyzer, it will give the user to pass the value of the pathGoPkg in a file (pathGoPkg.txt) from his repository, the code will check if this file exists, then it will read its content and assign it to the pathGoPkg variable, and use it instead of the current fixed path specified here

Sample usage for this code can be found in this branch, sample pathGoPkg.txt is under the govwa-gorepo1 folder

What are the relevant issue numbers?

#330678
