KQL bug in Events queries

[s4parke]

The query for "Warning events" has a case-sensitive KQL error and does not retrieve any results.

Warning events.kql:9

Events
| where EventLevelName == "warning"  // this does not work
| sort by TimeGenerated desc

Sampled values for the EventLevelName field are "Information", "Warning", "Error".

A likely source of this code sample is the Azure Monitor Reference page for the Event table.

I propose using a case-insensitive match for the field:

Events
| where EventLevelName =~ "Warning" 

The pattern can be found in several query files in this repo, for example:

1. Azure Services/Virtual machines/Queries/Errors/Error event on computer missing security co critical update.kql
2. Solutions/LogManagement/Queries/Diagnostics/Count of warning events.kql
3. Solutions/LogManagement/Queries/Diagnostics/Warning events.kql

Here are screenshots illustrating the values of EventLevelName.
