fix: connect git integration payload (CM-756)

[mbani01]

This pull request updates the way remote repository data is handled during Git integration authentication. The main change is to ensure that the remotes field in the integration payload is always an array of objects with a url and a forkedFrom property, rather than just an array of URLs.

Integration payload improvements:

• In gitAuthenticate.ts, the remotes field in the payload sent to IntegrationService.gitConnectOrUpdate is now transformed into an array of objects with url and forkedFrom: null properties, ensuring consistent structure for downstream processing.
