Zoom Chat Incomming Webhook enhancement

[Apipia]

Describe the problem

Add an alert option to send messages to ZoomChat

Proposed solution

ZoomChat webhook requires an Authorization token. Add support for adding an authorization token header to the request. Also ZoomChat has trouble rendering large json-formated (field) messages, so instead send text as plain-text. Create a new condition that checks for if ($this.systemtype -eq 'zoomchat')

Additional details

I already have written the code for this and can make a PR anytime.
