Add a Get-MgChangeLog cmdlet

[KirkMunro]

The Graph team just redesigned their change log page (not released yet), and added a bunch of filters to allow users to get the latest change log for various products, etc. so that they can see a filtered view, plus added an RSS feed for the ChangeLog. That's all great, but I'm a command-line oriented guy, and would love to see a Get-MgChangeLog cmdlet that does not require authentication that allows me to retrieve the entire change log or a filtered change log by using parameters to filter the data right in PowerShell. This would allow me to plug that cmdlet into my existing toolchain, solutions I have built on the Graph module bundle, etc. so that I can surface the change log details where it matters most in a manner that is useful to whoever needs the information.

This is a really interesting idea. I'd rather have this on Graph so you'd get the same experience (and we'd use the same generation experience). But the idea to highlight the changelog in our SDKs is clever and would be something we could look at. I wouldn't prioritize it super high, but something we should keep in our outlook.
