Update Microsoft Teams webhook

[thinkst-tom]

Proposed changes

Microsoft deprecated the URL format that was previously being used and have recently begun requiring that a particular URL format be used for Teams webhooks: https://default_some_hash_.ac.environment.api.powerplatform.com:443/powerautomate/automations/direct/workflows/...

If a webhook notification is enabled for a Canarytoken that matches this new format, an alert will be posted to the Teams channel that the URL has been configured for.

The payload format has also been updated to the newer and recommended AdaptiveCard format.

Further comments

The changes were tested by creating a Web Bug token and then triggering it, and manually creating a exposed key alert for a AWS API Key token. Each message was then checked on Teams to ensure it was being displayed correctly.

This is what the messages looked like before the change:

might be best to make this URL a constant and then refer to it?
