This pull request addresses issue #615 by standardizing the format of author names from "Lastname, Firstname" to "Firstname Lastname" in the Zenodo metadata processing. A new helper function reformat_author has been added to scripts/auto-add-zenodo-entry.py and integrated into the complete_zenodo_data function. Similarly, scripts/generate_link_lists.py now uses a new function format_author_name for this purpose. Additionally, the complete_zenodo_data function has been removed from scripts/generate_link_lists.py to eliminate duplication, and the version from scripts/auto-add-zenodo-entry.py is now directly used. These changes simplify code maintenance and improve the consistency of name formatting across the repository.

• scripts/auto-add-zenodo-entry.py Standardized author name format and removed duplicate code by consolidating complete_zenodo_data here.
• scripts/generate_link_lists.py Refactored author name formatting and removed the duplicate complete_zenodo_data function.
