build fails, need to update FSharp.Formatting about fsharpx.collections

[ronnieholm]

I'm not that familiar with FSharp.Formatting.

What is it about the latest FSharp.Formatting that would make GenerateHelp work? It seems packages/formatting/FSharp.Formatting/styles disappeared between commits b9cf8f3 and 24d1ff5 where FSharp.Formatting was updated from version 3.1.0 to 7.2.9.

Strange that running fake.cmd on my local machine executes the GenerateHelp target, but Appveyor does not.
The FSharp.Formatting version in paket.lock, 7.2.9, is still quite old. Commit 24d1ff5 most likely broke that target, but I relied on the successful Appveyor build and did not build that PR locally.

Actullay bringing the version forward to the most current release, 9.0.1, probably involves some work in build.fsx, I believe a lot has changed.

Pretty sure the problem dates from commit 24d1ff5d627f3751ac07a59b672b2b4ffcedca08, which updated FSharp.Formatting and FSharp.Formatting.CommandTool to v7.2.9 from v3.1.

Rolling back those 2 references via paket update caused a problem with the paket.lock file.

So I think the best way forward is fixing the build targets that use FSharp.Formatting to work with v7.2.9

This is not something I have the time to do anytime soon.
