Use AsyncTask thread-safe logging in GetMicrosoftNuGetPackagesMap

[Copilot]

GetMicrosoftNuGetPackagesMap runs on AsyncTask's background execution path but still logged through the obsolete Log property. This updates the task to use the thread-safe logging helper intended for AsyncTask implementations.

• Logging path

  • Replace the direct Log.LogMessage (...) call in GetMicrosoftNuGetPackagesMap.RunTaskAsync () with the inherited LogMessage (...) helper.
  • Keep the existing message text and exception handling behavior unchanged.

• Scope

  • Limit the change to the single background-thread logging site in GetMicrosoftNuGetPackagesMap.cs.
  • Leave task behavior, outputs, and cache handling untouched.

} catch (Exception ex) {
	LogMessage ("Could not download microsoft-packages.json: {0}", ex.Message);
}
