This example demonstrates how to enable custom validation patterns for webhook
URLs.

Of note:

- message is in Adaptive Card format
- default timeout
- package-level logging is disabled by default
- webhook URL validation uses custom pattern
  - allows use of custom/private webhook URL endpoints
- simple message submitted to Microsoft Teams consisting of formatted body and
  title

	// Set webhook url.
	webhookUrl := "https://outlook.office.com/webhook/YOUR_WEBHOOK_URL_OF_TEAMS_CHANNEL"

	// Add a custom pattern for webhook URL validation
	mstClient.AddWebhookURLValidationPatterns(`^https://.*\.domain\.com/.*$`)

	/*
		It's also possible to use multiple patterns with one call:

		mstClient.AddWebhookURLValidationPatterns(`^https://arbitrary\.example\.com/webhook/.*$`, `^https://.*\.domain\.com/.*$`)

		To keep the default behavior and add a custom one, use something like
		the following:

		mstClient.AddWebhookURLValidationPatterns(DefaultWebhookURLValidationPattern, `^https://.*\.domain\.com/.*$`)
