Migrating old endpoints to v2 API

[ZibanPirate]

Description

after merging #283 , the old code is still working (old controllers/services), we need to migrate them to the new code and expose the APIs under /v2, bellow are the tasks needed to accomplish this:

Check List

1. Call /v2/Contributors endpoint from frontend, instead of old endpoint /Contributors, and remove the last.
   • The API code for Contributors Controller get method is here
   • The Frontend code for calling the old endpoint is here and here
2. Create /v2/GithubUsers endpoint and call it from frontend instead of /github/users, and remove the last.
   • You will create a new method inside Github service similar to listContributors method, but the logic will be that of the old getUser method
   • You will create a new module api/src/github-user and inside you create your controller api/src/github-user/controller.ts similar to Contributors' controller. where you call the newly created method of GithubService.
   • Then update the frontend to call the new endpoint instead of the old one here and here
