Extend provisioning code for Aspire.Hosting.Azure.ApplicationInsights

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

I try to set the daily quota on an Application Insights instance but the required Bicep code is currently not generated .

### Describe the solution you'd like

Please add a 'Microsoft.Insights/components/pricingPlans@...' resource to the existing Aspire resource and make the properties available by an extension method WithPricingPlan(InsightsPricingPlanProperties properties).

One of these properties is "Cap" that takes the dailyQuota in GB.

### Additional context

The daily volume cap must be set on Log Analytics Workspace and Application Insights separately to prevent unforeseen costs on these Azure resources.
