feat: add line content to 2ms results (#249)

To analyse the entire value of the line where the secret was detected,
2ms now takes the `Line` information from gitleaks.

**Checklist**

- [x] I covered my changes with tests.
- [ ] I Updated the documentation that is affected by my changes:
  - [ ] Change in the CLI arguments
  - [ ] Change in the configuration file
