Remove the GitHub DTO

[Hemanthr1]

Issue Description

Remove the GitHub DTO from the codebase, as the functionality can be effectively managed using the JSON object received from GitHub.

Expected Behavior

The application should function as intended without the GitHub DTO, utilizing the JSON object directly instead.

Actual Behavior

The presence of the GitHub DTO introduces unnecessary complexity to the codebase.

I would like to get some clarity on this issue - where exactly is GithubDTO class located? Do you mean GithubRepositoryDTO instead?! @ironmark3 @Hemanthr1
