This is a great badge, but I think it is missing a rules file to work correctly?

Hi, I want to help this PR.

I don't know how to make and test the rules, so I just grep the output with httpie (jq and less to make it easier for me to debug) from fedmsg bus.

First, I want to know when it should be triggered.
I don't think that it depends on the bug status. (NEW, ASSIGNED, POST, MODIFIED, ON_QA, CLOSED, etc.)

I think it should be triggered when users (not others) modify the flag.fedora-review to +. Also it should be tied with bug_id, so it doesn't count as two or more instance.

for example:

{
  "action": "modify",
  "bug_id": 1988832,
  "change_set": "88799.1627967798.15325",
  "changes": [
    {
      "added": "+",
      "field": "flag.fedora-review",
      "field_name": "flag.fedora-review",
      "removed": ""
    }
  ],
  "routing_key": "bug.modify",
  "target": "bug",
  "time": 1627967798,
  "user": {
    "id": 415022,
    "login": "didiksupriadi41@gmail.com",
    "real_name": "Didik Supriadi"
  },
  "who": "didiksupriadi41@gmail.com"
}

While this badge was a nice idea, the PR is open for six years without a rules file. Without a rules file, this badge cannot exist. I am closing the PR.
