Integrating the main pattern repositories for Web

Is your feature request related to a problem? Please describe.
Ensuring we are building fully on existing work and the wider state of the art
Describe the solution you'd like
Integrate the following links, which add up to c.200 patterns:

https://sustainablewebdesign.org/

https://github.com/cnumr/best-practices

https://gr491.isit-europe.org/en/

https://almanac.httparchive.org/en/2022/sustainability

Describe alternatives you've considered
I looked for signs that these were already being considered but was not aware of any connections, although I might have missed them.

Additional context
At W3C there is a project underway to create a WCAG equivalent for sustainable web design, which seems to overlap closely with this project. Might be worth more formal collaboration (e.g. having people in each other's process)

Discussed in today's meeting. We'll proceed after COP. This could be a potential task for Upwork people.
