If this PR adds a new package to the archive, please note:
New packages added to the minotaur archive are always published in version 1.0.0.
This means that any and all changes made to the package during the review process, should only bump the Minor or Patch version of the package.

PR checklist:

• The package description has been updated to the title of the paper.
• This package contains a BibTex file.
• The month field in the BibTex file is formatted as a three letter code.
• If this package already exists in the community archive:
  • The information from the community archive was used to fill-in empty janno fields (if applicable).
  • The commands used for the fill-in and any tool versions are kept track of in the README file.
  • The BibTex key used for the citation is identical to that in the corresponding package in the community archive.
  • The DOI in the BibTex file is identical to the one used in the corresponding package in the community archive.
• If the janno information was collected manually:
  • Add any additional contributors to POSEIDON.yml
• Any scripts/commands used to prepare the pacakge are kept track of in the README file.
• Country information is also present in the Country_ISO column.
• Any columns in the janno that are entirely missing or n/a should be removed from the janno.
• Poseidon_IDs in the Relation_To column contain the _MNT suffix.

Once the Pull Request has passed the review process, ensure the package version is bumped once more before publishing with:

trident rectify -d <package_dir> --logText 'Bump version for release' --packageVersion Major --checksumAll

The bibTex key here is different from the one on the community archive (GretzingerNature2022 instead of Gretzinger2022) but the community archive one does not follow the Poseidon specification (see context-information section)

OK great. Thanks. Just one comment:

1. In the Relation_To column you currently have non-existent Poseidon_IDs. For example ADN003_MNT doesn't exist, but ADN003_ss_MNT does, so this needs correction.

[TCLamnidis]

Done!
