SynchronizationException due to missing or null head_branch field in GitHub Actions JSON response during pipeline synchronization

[davidsouza-protex]

Describe the bug
When synchronizing a GitHub Actions pipeline in the project, the synchronization process fails due to a DecodeException caused by a missing or null head_branch value in the JSON response. The synchronization attempt leads to a SynchronizationException.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Project Synchronization Page'.
2. Click on 'Start Synchronization' for the GitHub Actions pipeline.
3. Observe the error message in the logs indicating a DecodeException due to the missing head_branch field.

Expected behavior
The synchronization should complete successfully without any errors, fetching all relevant data from the GitHub Actions pipeline.

Desktop (please complete the following information):

• OS: MacOS
• Browser: Chrome
• Version: 125

Additional context
The synchronization error occurs specifically due to a missing head_branch field in the response data. This field is required but is currently null or missing in the GitHub API response, leading to a decoding failure when processing the pipeline runs.
