converting to draft:

• check if some of the new contributors have a github account (I know some do)
• need to add a few more contributors from some recently developed BIDS tools

[Remi-Gau]

TODO (but for future PRs):

• add github usernames to contributors who have one
• update affiliations (help to know where our contributors are from)
• check people who have contributed to repos on BIDS and BIDS apps github organization, tools / converters repos...
• check people mentioned on BIDS papers (that probably should be listed as contributors ?)
