Update templates with latest refinements (#763)

This change has following:

1. Make them similar as current state of prod
[manifest](https://msazure.visualstudio.com/One/_git/AzureMonitorResourceProviderOnboarding?path=/src/resourceproviders/microsoft.containerservice/managedclusters/prod/manifest.json)
, basically removing some alerts according to the
[PRD](https://microsoft.sharepoint.com/:w:/r/teams/azurecontainercompute/_layouts/15/Doc.aspx?sourcedoc=%7BD7733B7A-2BD1-4F09-95C7-9A114B4A8055%7D&file=Recommended%20Alerts%20PRD.docx&wdLOR=cF191ECF1-3BEC-4012-BC1F-C5CF1CBD4365&fromShare=true&action=default&mobileredirect=true)
2. Update description links to aka ms
3. Change long sentence alert names to Single words
4. Update the bicep template same as Arm template


I will create a Tip PR in manifest for points 2 and 3 above.
