Deploy FSharp.Core.xml in our IDE package

[cartermp]

fixes #2926

[cartermp]

Just to clarify, if I move the xml file in the directory that I think does setup definitions for, I get XML docs for FSharp.Core. So I know that works, it's just a question of if this is the correct fix

This change is the same as placing that XML file locally at C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\CommonExtensions\Microsoft\FSharp\FSharp.Core.xml, so if that manual step does what you want, then this will do what you want, too.

Yep, that's totes what I want. Here's the difference.
