[feature] List of individuals in each WP

From https://github.com/EVERSE-ResearchSoftware/EVERSE-ResearchSoftware.github.io/pull/160#issuecomment-3479309550

> Just a bit of background - we did think it would have been useful to show individuals associated with each WP, which is why we used the wpX: true tags. However, that wasn't ever implemented.
