Parse manifest.contributors to fill in the RO-Crate

[muffato]

Here I want to include all information from the manifest.contributors field into the RO-Crate contributor list:

• name
• affiliation
• ORCID
• GitHub handle
• role

That's a new function named parse_manifest_contributors. I've kept the updated original code that parses manifest.author for backwards compatibility in parse_manifest_authors as it also serves as a fallback.
add_main_authors is now first a dispatcher method for the two aforementioned methods, before adding the returned contributors to the RO-Crate

Pull request overview

This PR extends the RO-Crate generation logic to populate the crate contributor/person entities using the full manifest.contributors structure (name, affiliation, ORCID, GitHub, role), while keeping manifest.author parsing for backwards compatibility.

Changes:

• Prefer manifest.contributors over manifest.author when adding people/roles to the RO-Crate workflow entity.
• Add parsing + normalization for manifest.contributors (field trimming, URL normalization, email backfilling from git).
• Expand RO-Crate tests to cover contributor parsing, role mapping, and fallback behavior.
