[Cherrypick] Update onebranch Dockerfile for windows agent #2159 to release/0.11 (#2160)

Cherrypick #2159 to `release/0.11`

## Why make this change?

- We were getting the error message "no matching manifest for
windows/amd64 10.0.20348 in the manifest list entries".
- the problem is that the Docker image we're trying to pull
(mcr.microsoft.com/dotnet/aspnet:6.0-cbl-mariner2.0) does not support
the architecture of our Docker host (Windows/amd64).
- The 6.0-cbl-mariner2.0 tag of the dotnet/aspnet image is designed for
the CBL-Mariner (Common Base Linux) operating system, which is a Linux
distribution developed by Microsoft. This image will not work on a
Windows host of our onebranch pipeline.

## What is this change?
- changed the base images from Linux-based images to Windows-based
images.
- `mcr.microsoft.com/dotnet/aspnet:6.0`

## How was this tested?

- [X] pipeline passing
