New Incident Alert playbooks with links to new portal

[briandelmsft]

Change(s):

• Created 2 new playbooks for incident alerting
• 1 Playbook sends an email alert with modern template including links to the XDR portal
• 1 Playbook sends a teams adaptive card with modern template and links to the XDR portal
• Both playbooks include entity level linking where possible, such as account entities to the XDR user page, and device entities to the XDR Device page

Reason for Change(s):

• The existing playbooks are centered around the Azure Portal, while things are moving the security.microsoft.com portal. Given that the old portal will be deprecated, a new template is needed. These new playbooks are more modern in design, provide more entity information, and link the security.microsoft.com portal at the incident and where appropriate the entity level as well.

Version Updated:

• N/A

Testing Completed:

• Deployment tested
• Permissioning tested
• Email template tested
• Teams card tested
