* Naming of class constants
This is in preparation of enforcing a naming convention for constants in classes/interfaces. At the end, the following lint rule shall be set:
```json
"class_attribute_names": {
"constants": "^C_.+$",
...
},
```
After this, the only remaining constants not following this rule are in `zcl_abapgit_version`.
* Update zif_abapgit_dot_abapgit.intf.abap
* Update zcl_abapgit_gui_chunk_lib.clas.abap
* Update zcl_abapgit_gui_router.clas.abap
