Change SAST log messages and update config default root

[Or-Geva]

• All tests passed. If this feature is not already covered by the tests, I added new tests.
• I used npm run format for formatting the code before submitting the pull request.

• Remove leftovers from JasRunners log message and fix an issue where the SAST log message shows undefined for skip-folder
• When examining the JFrog Applications Config, note that the source_root has an incorrect default value when using debug mode. Essentially, this issue arises in debug mode when a configuration file exists without source_root, leading to the use of the original VSCode extension source code instead of the current project used in debug mode. The underlying cause of this problem can be traced back to the use of __dirname.
