Register Payload CMS as a Digital Public Good (DPG)

[MurzNN]

As Payload CMS is licensed under the MIT License, it would be great to register it as a Digital Public Good (DPG), to improve the global visibility, recognition, credibility, and trust!

The steps to achieve this are described on the page https://www.digitalpublicgoods.net/digital-public-goods/submission-guide

And even now, Payload CMS suits most of them pretty well!
