(GH-10780) Fix example in about_Intrinsic_Members

[michaeltlombardi]

PR Summary

Prior to this change, about_Intrinsic_Members defines examples that describe a hashtable and interacts with a variable containing the hashtable but doesn't define the hashtable itself in the code blocks. The examples also use -Type with the Get-Member cmdlet, which is an alias for the paramter canonically named MemberType.

This change:

• Defines the $hash variable in the first code block for the example, ensuring readers can follow along without needing to intuit the definition from the output.
• Replaces usage of the -Type alias parameter with the canonical parameter name MemberType, making it easier for readers to look up the parameter. This also adheres to the docs style guide.
• Resolves Missing information in the Example section of about_Intrinsic_Members #10780
• Fixes AB#198703
