proposal: create an ARCHIVE.MD

[switchupcb]

Instead of removing projects, it may be useful to archive them. This can be implemented using a bot that (on update):

1. Parses raw markdown from README.MD: https://github.com/yuin/goldmark
2. Checks library URLs with the Github API for archive status: https://docs.github.com/en/rest/repos/repos#get-a-repository
3. Remove archived libraries from the README (delete the line from the MD).
4. Add the removed library to the ARCHIVE.

Instead of "deleting" the line, simply iterate line by line and include it when necessary.

var ARCHIVE strings.Builder
var README strings.Builder

// content represents the lines or file.
for _, line := range content {
    repo := getRepository(line)

    // add conditions where necessary
    switch {
      case repo.archive:
        ARCHIVE.WriteString(line)
      default:        
        README.WriteString(line)
    } 
}

You could also add reasons for archive in that README such as archived, standards, etc.

Just adding to this, the current process is manual.
Usually when a project is archived it's eol (abandoned) and thus in such cases a community/other fork will replace the one in the readme if there is one.
This is the more important part where we need to focus, I believe than to maintain a list of old abandoned projects.
