feat: add enforcer EnableAcceptJsonRequest feature (#119)

Version of the "Casbin" module upgraded to 2.100 to access the "bleAcceptJsonRequest" feature then integrated this project with the new version of the "Casbin" then added new requested feature.

Changes:
- Upgraded the version of the "Casbin" module
- Integrated with the new version of the "Casbin" module
- Changed the .proto file to add "EnableAcceptJsonRequest" field at calling NewEnforcer
- Generated Go files from new changed the .proto file
- Added "EnableAcceptJsonRequest" field to each "NewEncoder" test cases
