Auto detect latest git tag if no version is specified

[JohT]

🚀 Feature

• Follow symbolic links when collecting package.json files. If you use symbolic links in the "source" directory to avoid copying git repositories you might already have downloaded, the package.json files will now be detected correctly.
• Auto detect latest tag if no version is specified. If you are using the example analysis scripts like
  analyzeAxonFramework.sh, analyzeAntDesign.sh, analyzeReactRouter.sh, then you don't have to specify the version number. In case it isn't given, the latest git tag will be automatically detected and used for that.

🛠 Fix

• Fix typo in info log entry.
