Fix parseGoModule function to use strings.SplitSeq and improve efficiency

- Update parseGoModule to use strings.SplitSeq for better performance
- Change GoModule.Module field to GoModule.Name for consistency
- Use strings.CutPrefix instead of HasPrefix + TrimPrefix pattern
- Add early break after parsing go version line
- Update template references to use .GoModule.Name instead of .GoModule
