bug: K8s Prepare job webhook fails to create a pod for two services that use the same image

[DenisPalnitsky]

Prerequisites

Have Actions Runners Controller with AutoscalingRunnerSet configured in Kubernetes mode

Steps to reproduce

1. Create workflow

   
   name: CI
   on:  
   push:   
   workflow_dispatch:

jobs: build:
container: image: ghcr.io/actions/actions-runner:latest

services:
  redis:
    image: redis:6.2.5

  redis01:
      image: redis:6.2.5

runs-on: [MY_ACTIONS_RUNNERSET_NAME]
steps:
  - run: echo "Hello, world!"
    name: echo

Note that we want to use two redis service one with `redis` and other `redis01` and that's how we want to reach them from workflow.

2. Run workflow

## Expected Result
Workflow executed.

## Actual result
Workflow fails on  `Initialise containers` step  with error

I checked the args that prepareJob function receives and it does not have unique 'name'

  "services": [
        {
            "image": "redis:6.2.5",
            "dockerfile": null,
            "entryPointArgs": [],
            "entryPoint": null,
            "workingDirectory": null,
            "createOptions": null,
            "registry": null,
            "environmentVariables": {},
            "portMappings": [],
            "systemMountVolumes": [],
            "userMountVolumes": []
        },
        {
            "image": "redis:6.2.5",
            "dockerfile": null,
            "entryPointArgs": [],
            "entryPoint": null,
            "workingDirectory": null,
            "createOptions": null,
            "registry": null,
            "environmentVariables": {},
            "portMappings": [],
            "systemMountVolumes": [],
            "userMountVolumes": []
        }
    ]

I guess we need to add names to that code that passes those args first.
