Is Linux arm64 images supported in App Services?

Recently we changed our Dockerfile of our .NET 6 app to build with the arm64 runtime:

`FROM mcr.microsoft.com/dotnet/aspnet:6.0-bullseye-slim-arm64v8 AS base`

However, when the new image is deployed and started in its App Service container, it fails with the error:

```
INFO - Initiating warmup request to container xx-main_0_edd83162 for site xx-main
ERROR - Container xx-main_0_edd83162 for site xx-main has exited, failing site start
ERROR - Container xx-main_0_edd83162 didn't respond to HTTP pings on port: 80, failing site start. See container logs for debugging.
INFO - Stopping site xx-main because it failed during startup.

standard_init_linux.go:228: exec user process caused: exec format error

```

Sad to say, but the same image works in AWS ECS...
