Fix GetSchema EmbeddedResource: use Assembly.Load instead of AppDomain search

[Copilot]

GetSchema() on an XmlProvider with EmbeddedResource was failing at runtime with KeyNotFoundException because AppDomain.CurrentDomain.GetAssemblies() |> Array.find couldn't locate the target assembly when called from a different assembly (e.g. a test project referencing the one containing the type).

Changes

• Helpers.fs: Replace AppDomain.CurrentDomain.GetAssemblies() |> Array.find (fun a -> a.GetName().Name = asmName) with System.Reflection.Assembly.Load(asmName), which resolves the assembly whether or not it has already been loaded into the AppDomain.

// Before — fails if assembly not yet loaded in AppDomain
let loadedAsm =
    System.AppDomain.CurrentDomain.GetAssemblies()
    |> Array.find (fun a -> a.GetName().Name = asmName)

// After — loads on demand
let loadedAsm = System.Reflection.Assembly.Load(asmName)

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.worldbank.org
  • Triggering command: /usr/share/dotnet/dotnet /usr/share/dotnet/dotnet /usr/share/dotnet/sdk/8.0.123/FSharp/fsc.dll @/tmp/MSBuildTempw6V7WL/tmp3a6ea14669e740cca472a3c6310bd265.rsp (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
