Google Chat webhook kind

[fraserhess]

I'm requesting support for Google Chat webhooks as a kind. The generic messages result in an HTTP 400 error because there's only two fields supported in the payload by Google Chat: text and thread.

The text field supports some basic formatting: newlines, bold, italics, strikethrough, monospaced, monospaced block, bulleted list, and hyperlinks.

Example curl command:

curl -X POST "https://chat.googleapis.com/v1/spaces/XXXXX/messages?key=YYYYYY&token=ZZZZ" -H "Content-Type: application/json; charset=UTF-8" -d '{"text":"# Hello *team*!\nThis message was sent via curl."}'

A full URL to a test space in Google Chat can be provided privately for testing.

There is also a cardsV2 option that creates richer output and experiences but the JSON is much more complex

{
  "cardsV2": [
    {
      "cardId": "FA2F044B-ADA4-422A-8470-D1468511BED1",
      "card": {
        "header": {
          "title": "Setup Manager: Started",
          "subtitle": "MacBook Pro"
        },
        "sections": [
          {
            "header": "Details",
            "collapsible": false,
            "widgets": [
              {
                "decoratedText": {
                  "topLabel": "Serial",
                  "text": "DHGG6LQFW2"
                }
              },
              {

                  "topLabel": "macOS",
                  "text": "26.2 (Build 25C5048a)"
                }
              }
            ]
          }
        ]
      }
    }
  ]
}
