SecurityInsights 3.0.1 New-AzSentinelAlertRule requires DisplayName within internal/back-end, but cannot supply in module

### Description

Running the New-AzSentinelAlertRule with the documented parameterset for MicrosoftSecurityIncidentCreation kind rules, results in a missing parameter error due to the required "DisplayName" parameter being limited to only NRT or Scheduled rules through ParameterSets.

Example code to enable Azure AD Identity Protection incident creation rule:

```
New-AzSentinelAlertRule -ResourceGroupName:"resourcegroup" -WorkspaceName:"workspace" `
-Kind:"MicrosoftSecurityIncidentCreation" -Enabled `
-AlertRuleTemplateName:"532c1811-79ee-4d9f-8d4d-6304c840daa1" `
-ProductFilter:"Azure Active Directory Identity Protection"
```

**Expected Result:** "Create incidents based on Azure Active Directory Identity Protection alerts" rule is created

**Actual Result:** Rule not created & errors shown.

**Additional commentary:**

There appears to be several other issues with the MicrosoftSecurityIncidentCreation kind within this module too ($AlertRule.Enabled has the ability to be set to non-switch parameters multiple times - looks like a copy/paste error), which may need reviewing.

A fork of New-AzSentinelAlertRule with DisplayName introduced into the parameterset and associated code to handle within the MSIC codeblock resolves this issue.

Inspect New-AzSentinelAlertRule.ps1 around line 676 and the parameter-set definitions for MicrosoftSecurityIncidentCreation. Reproduce the supplied command, trace how its properties are built, and confirm the completed command includes displayName and successfully creates the rule.
