Clarify relation with Microsoft.Maui.Graphics nuget package

[piju3]

It seems many people who are looking to use the Microsoft.Maui.Graphics package end up on this page (myself included). Given that it's in the dotnet namespace with a matching name, and that it has a link back to the NuGet package, people naturally assume that this is the repository it's built from, which causes confusion.

From what I understand, the source for the current package can be found at https://github.com/dotnet/maui/tree/main/src/Graphics/src/Graphics and the documentation at https://learn.microsoft.com/en-us/dotnet/maui/user-interface/graphics/. It would be good if the description explicitly mentioned this and the nuget badge was removed.

HI @piju3, I think this is the answer: #496 (comment)

in Jan mattleibow said this repo has moved to https://github.com/dotnet/maui

I agree the readme, contributing.md, and nuget package URLs should be updated.

The authors should also consider disabling issues and PRs in this repository.
