Update pyDataverse version and upload check

[JR-1991]

This pull request adds a safeguard to prevent double uploads of the same dataset and updates the pydataverse dependency. The main changes include introducing a check in the upload method to raise an error if a dataset has already been uploaded, and adding a corresponding integration test to verify this behavior.

Dataset upload protection:

• Added a check in the upload method of easyDataverse/dataset.py to raise a ValueError if p_id is not None, preventing double uploads of the same dataset. The error message guides users to use the update method or reset p_id if needed.
• Added an integration test test_double_upload_raises_error in tests/integration/test_dataset_creation.py to ensure that attempting to upload a dataset twice raises a ValueError.

Dependency update:

• Updated the pydataverse dependency version from 0.3.1 to 0.3.4 in pyproject.toml for improved compatibility and bug fixes.
