Missing the description for some properties & events of DataSet control

[Zheng-Li01]

• .NET Core Version:
  NET SDK 6.0.100-alpha.1.20609.2

• Have you experienced this same bug with .NET Framework?:
  No

Minimal repro:

1. Create a .NET Framework winforms project with a DataSet contorl.(or open the attached application
   NewIssueDataSet.zip).
2. Migrater the dataSet1 contorl to core project,
3. Observe the different description for some properties & events of dataSet1 control between .Net Framework project and Core project.

Expected behavior:
There have the correct description for some properties & events of dataSet1 control in core project.

Actual behavior:
Missing the description for Initialized & MergeFailed events, and CaseSensitive/DataSetName/EnforceCOnstraints/Locale/Namespace/Prefix/Relations/Tables properties.

[RussKie]

This is a regression in .NET Core, in which description attributes have been removed from the DataSet API.

E.g. MergeFailed event is decorated in .NET Framework, but the same decoration is missing in the .NET Core/.NET versions:

runtime/src/libraries/System.Data.Common/src/System/Data/DataSet.cs

Lines 1034 to 1037 in 34cae74

	/// <summary>
	/// Occurs when attempting to merge schemas for two tables with the same name.
	/// </summary>
	public event MergeFailedEventHandler? MergeFailed;
