Describe the bug When trying to use RPRrovider from a .fsx file in an fsdocs docs project,

To Reproduce Steps to reproduce the behavior:

1. Start a new fsdocs project.
2. Add a script with the below content.
3. Run script in dotnet fsi, then run in dotnet fsdocs watch.

#r "nuget:RProvider"

open RProvider
open RProvider.Operators
open RDotNet

try
    // R.pi |> ignore
    R.``+``([ 1.; 2. ]) |> ignore
    // R.abs(1.) |> ignore
    // printfn "%A" <| RProvider.datasets.R.volcano.GetValue<string>()
with
    | (e:exn) -> 
        printfn "Exception thrown: %s" e.Message
        printfn "Trace was: %s" e.StackTrace
(*** include-fsi-merged-output ***)

Expected behavior The script should return the same html string in both dotnet fsi and dotnet fsdocs watch.

Environment (please complete the following information):

• OS: macOS
• OS Version: Sonoma
• Using in script or library: fsdocs
• RProvider Version 2.1.0
• Installed R Version 4.1.1

Additional context The exception thrown is as follows:

System.ComponentModel.Composition APIs are not supported on this platform.

It works with R.pi or R.abs(1.), but not more complex interactions. It seems to be related to the GetValue member on SymbolicExpression.

Querying the loaded assemblies with reflection, it seems to think that System.ComponentModel.Composition, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 is the loaded assembly version.
