Runtime for Template Resource undefined or unspecified for dotnet8 function

[boyersnet]

Problem

Unable to launch vscode debugging configuration with dotnet8 lambda function. Function uses Lambda Annotations. Function executes properly when using sam local invoke.

Steps to reproduce the issue

Migrating from existing dotnet6 launch configuration with target: template immediately get the following error:

[ERROR]: SamLaunchRequestError: Invalid launch configuration: Runtime for Template Resource [ResourceId] in Template file [Template Path] is either undefined or unsupported. [BadLaunchConfig]

        "templatePath": "${workspaceFolder}/[path]/template.yaml",
        "logicalId": "[ResourceId]"
      },
      "sam": {

      },
      "lambda": {

            "remoteRoot": "/var/task"
          }
        ],
        "payload": {
