fix: prevent 'None' git service in CI uploads

[sentry]

This PR addresses an issue where the git_service parameter could be None during an upload, leading to the literal string "None" being interpolated into the upload URL. This caused a Pydantic validation error on the backend, as "None" is not a valid git service.

The root cause was that the _get_git_service method in CI adapters often returned None (the default from the base class), forcing reliance on git ls-remote parsing of the remote URL. This parsing can fail in environments with non-standard or proxied git remote URLs.

To fix this, _get_git_service has been overridden in the following CI adapters to provide a reliable git service based on the CI environment:

• GithubActionsCIAdapter: Returns "github"
• GitlabCIAdapter: Returns "gitlab"
• BitbucketAdapter: Returns "bitbucket"
• HarnessAdapter: Attempts to parse the git service from various Harness/Drone environment variables, falling back to None if unsuccessful.

These changes ensure that for common CI environments, a valid git service is provided, preventing the None value from reaching the URL construction and causing the validation error.

Fixes CLI-H5
