initial release, production ready

Works like expected

• self-hosted gh-runner without running with root possible ( docker causes sometimes issues)
• eleventy-plugins like @11ty/eleventy-img can be used

Example Workflow:

name: 11ty build
on: [push]
jobs:
  build_deploy:
   runs-on: self-hosted
   steps:
   - name: Checkout last commit of repository
     uses: actions/checkout@v3
   - name: Install 11ty and build website
     uses: extrawitz/11ty-dockerless-build@v1
   - name: Deploy
     uses: peaceiris/actions-gh-pages@v3
     with:
      publish_dir: public
      publish_branch: website
      github_token: ${{ secrets.PSA }}
