ubi9/dotnet-100 images use / as WORKDIR?

[AThomsen]

Consider this

➜  ~ podman run registry.access.redhat.com/ubi8/dotnet-90-runtime pwd
/opt/app-root/app

➜  ~ podman run registry.access.redhat.com/ubi9/nodejs-24-minimal pwd
/opt/app-root/src

➜  ~ podman run registry.access.redhat.com/ubi8/dotnet-90-runtime pwd
/opt/app-root/app

➜  ~ podman run registry.access.redhat.com/ubi9/dotnet-100-runtime pwd
/

➜  ~ podman run registry.access.redhat.com/ubi9/dotnet-100-aspnet pwd
/

Upgrading from ubi8/dotnet-90 to ubi9/dotnet-100 now causes all program files to be placed in / when build with COPY . . in a Dockerfile !!

Sorry for the inconvinience @AThomsen.

We intentionally changed the WORKDIR from being Red Hat specific to match the path used in Microsoft .NET runtime images and images from other vendors.

I'll look into having this change added to our .NET 10 container release documentation.
