Build Documentation Test Fails Due to "Bad Credentials" Error

### Describe the bug

The `Build documentation / build / build_main_documentation (push)` job is consistently failing during the "Syncing repository" step. The error occurs when attempting to determine the default branch name, resulting in "Bad credentials" errors.

### Steps to reproduce the bug

1. Trigger the `build_main_documentation` job.
2. Observe the logs during the "Syncing repository" step.

### Expected behavior

The workflow should be able to retrieve the default branch name without encountering credential issues.
