Unable to dynamically set pod name in pipeTransport

Re-opening from: https://github.com/microsoft/vscode/issues/100831

I am trying to debug kubernetes dotnet core pods (running vscode in wsl2) and it works if I hard code the pod name in, but using an acceptable Linux command to retrieve it does not (see below):
```
{
"name": "Attach in k8s",
"type": "coreclr",
"request": "attach",
"processId": "${command:pickRemoteProcess}",
"justMyCode": false,
"requireExactSource": false,
"pipeTransport": {
"pipeProgram": "kubectl",
"pipeArgs": [
"exec -i -n my-service $(kubectl get pods -n my-service -o name | grep -Po '\\\/\\K.+') --"
],
"quoteArgs": false,
"debuggerPath": "/vsdbg/vsdbg"
},
"sourceFileMap": {
// For debugging you must copy source code into the app folder and point at the local folder with those
// source items
"/app": "${workspaceFolder}/MyService.Web"
}
}
```

It randomly tells me valid kubectl flags don't exist. I have tried to use pipeTransport.pipeEnvs with no luck as it is not documented. I have tried to use input variables also with no luck here. Also environment variables have not been able to resolve this. Lastly, creating a prelaunch task did not set an environment variable for me to use here.
