docs/github.md needs better build example

[jarofgreen]

Says "python staticpatch"

Should say "python site.py build"

[jarofgreen]

And don't need ".htaccess" in zip stage

Also the github refs for branches are wrong.

This gives you branch name only:

${GITHUB_HEAD_REF:-${GITHUB_REF#refs/heads/}}

And in delete think we need

github.event.ref != 'refs/heads/main'

ALso change round filename eg live-deploy.yml preview-delete.yml preview-deploy.yml
