see also #501 for a potential archival of resources in general. If we keep resources, these links should be:

• Updated to their current URL
• if no current URL can be found, but the resource is very useful, we should link to a copy on wayback machine
• otherwise, remove the link

List of links that do not work anymore:

• https://cardsforhumanity.idean.com/ (suggestion: archive)
• https://old.vi.to/designers-and-women-in-open-source.html (suggestion: archive)
• https://voiceandtone.com/ (suggestion: archive)
• https://icons.mono.company/ (suggestion: delete)
• https://www.npmjs.com/package/react-feather (imho if we start to link to react packages, it might become overwhelming, so delete?) (suggestion: delete)
• https://osp.kitchen/foundry/ (times out) (only temporarily unavaliable, keep link as is)
