Loading resource packages transactionally via drag-and-drop no longer works

[jumpinjackie]

I suspect something in the UploadPackage method (that wraps the APPLYRESOURCEPACKAGE mapagent API) broke during the upgrade to .net 6.0.

It isn't a deal-breaker from an end user's perspective as there are adequate workarounds:

1. Load the package non-transactionally
2. Use the MG Site Administrator to load the package

More data points:

• Our setup code for APPLYRESOURCEPACKAGE is not working
• However, setup code for operations that involve file uploads like SETRESOUIRCE and SETRESOURCEDATA are working

So there must be something wrong in the setup code and we should change the APPLYRESOURCEPACKAGE setup code to more align with how SETRESOURCE and SETRESOURCEDATA do it
