deploying statically generated site

[lambtron]

would be cool if we could allow github action yaml file to look like this:

- uses: denoland/deployctl@v1
        with:
          project: example-deno-eleventy
          static: _site

instead of:

- uses: denoland/deployctl@v1
        with:
          project: example-deno-eleventy
          entrypoint: https://deno.land/[email protected]/http/file_server.ts
          root: _site
