Example for separate docs at other branch

There are two branchs in repo myproject, branch master and branch docs.

The program source at branch master.

The Sphinx documentation source at branch docs.

To build GitHub Pages from branch docs, add workflow to branch docs only.

1. switch to branch docs

2. add file ./.github/workflows/example-sphinx.yml

   on: [push]
   
   jobs:
     build:
       name: Sphinx Pages Test
       runs-on: ubuntu-latest
       steps:
         - uses: seanzhengw/sphinx-pages@master
           id: sphinx-pages
           with:
             github_token: ${{ secrets.GITHUB_TOKEN }}
             create_readme: true
   

3. commit

4. push docs

5. wait for the workflow
