Make NX_TASK_TARGET_CONFIGURATION environment variable available to runtime cache inputs

[mvgijssel]

Similar to #20949 expose $NX_TASK_TARGET_CONFIGURATION to make it available for runtime cache inputs. I have a target test configuration which is different for local VS CI.

{
  "name": "internal-dns",
  "projectType": "library",
  "sourceRoot": "libs/internal-dns",
  "targets": {
    "test": {
      "executor": "nx:run-commands",
      "options": {
        "command": "kuttl test",
        "cwd": "libs/internal-dns",
        "start-kind": false,
        "skip-cluster-delete": true,
        "configurations": {
          "CI": {
            "start-kind": true,
            "skip-cluster-delete": false
          }
        }
      },
      "cache": true,
      "inputs": [
        "{projectRoot}/**/*",
        "!{projectRoot}/kind-logs-*/**/*",
        "!{projectRoot}/kubeconfig",
        {"env": "NX_TASK_TARGET_CONFIGURATION"}
      ],
      "outputs": []
    }
  },
  "tags": ["type:library", "scope:infrastructure", "platform:kubernetes"]
}

When I invoke

nx test internal-dns
nx test internal-dns --configuration CI # <--- this one is cached

I want the second invocation to not use the cache.

Currently workaround is setting the environment variable NX_TASK_TARGET_CONFIGURATION=CI inside the CI.
