PowerShell Core cannot start a PS Job in .NET Core SDK Alpine image

Describe the bug

There appears to be a regression of issue #1922

docker run  -it --rm mcr.microsoft.com/dotnet/sdk:9.0-alpine pwsh -Command "& { Start-Job { 'test' } | Receive-Job -Wait }"
OpenError: [localhost] An error occurred while starting the background process. Error reported: An error occurred trying to start process '/usr/share/powershell/.store/powershell.linux.alpine/7.5.3/powershell.linux.alpine/7.5.3/tools/net9.0/any/pwsh' with working directory '/'. No such file or directory.

[admin@tenable-umwey6bv docker-ci-powercli]$ docker run  -it --rm mcr.microsoft.com/dotnet/sdk:8.0-alpine pwsh -Command "& { Start-Job { 'test' } | Receive-Job -Wait }"
OpenError: [localhost] An error occurred while starting the background process.

The fix shown in the declined PR for issue 1922 (replacing $PSHOME/pwsh with /usr/bin/pwsh) fixes the issue for me

Which .NET image(s) are you using?

mcr.microsoft.com/dotnet/sdk 8.0-alpine 2827d64f3133

Steps to reproduce

docker run -it --rm mcr.microsoft.com/dotnet/sdk:9.0-alpine pwsh -Command "& { Start-Job { 'test' } | Receive-Job -Wait }"

docker run -it --rm mcr.microsoft.com/dotnet/sdk:8.0-alpine pwsh -Command "& { Start-Job { 'test' } | Receive-Job -Wait }"
