Update coder templates automatically

1. Create a GitHub secret named CODER_SESSION_TOKEN with your coder session token You can generate a long lived session token by running the following command in your browser console while logged into Coder with a Template Admin or Owner role.

     coder token create --lifetime 8760h --name "GitHub Actions"

2. Create a .github/workflows/push-coder-template.yaml file and use one of the examples below.

1. Update a Coder template with the latest commit hash as the version name, commit message as the update message and mark this as active.

   name: Update Coder Template
   
   on:
     push:
       branches:
         - main
   
   jobs:
       update:
           runs-on: ubuntu-latest
           steps:
           - name: Checkout
             uses: actions/checkout@v3
           - name: Get latest commit hash
             id: latest_commit
             run: echo "hash=$(git rev-parse --short HEAD)" >> $GITHUB_OUTPUT
           - name: Get commit title
              id: commit_title
              run: echo "title=$(git log -1 --pretty=%B)" >> $GITHUB_OUTPUT
   
   
           - name: Update Coder Template
               uses: matifali/update-coder-template@v3
               with:
                   id: "my-template"
                   dir: "my-template"
                   url: "https://coder.example.com"
                   name: "${{ steps.latest_commit.outputs.hash }}"
                   message: "${{ steps.commit_title.outputs.title }}"
                   coder_session_token: ${{ secrets.CODER_SESSION_TOKEN }}

2. Update a Coder template with a random version name without activating.

   on:
     push:
       branches:
         - main
   
   jobs:

           runs-on: ubuntu-latest
           steps:
