Installation of FSLS with dotnet tool

[tani]

Hello,

I propose a new installation with dotnet tool. This method is used by some official utilities such as dotnet-try, and a few F# projects. FAKE is one example.

Pros:

• Each plugin can call the API without a specific script. It is dotnet tool install fsharp-language-server.
• Quite simple to install FSLS alone.

Cons:

• The project should be uploaded on NuGet.
• They cannot use nightly build with this method.

Second pros., is important for using FSLS with emacs and vim plugins such as vim-lsp, ALE and eglot. Do you have any plan to distribute binary build with dotnet tool?

Thanks.

P.S. I also post this proposal to FSAC.
