Fix missing GitHub Pages configuration

[nickserv]

Without this, using actions/deploy-pages on a repository will fail unless the user has manually configured GitHub Pages to use GitHub Actions in the repository's settings:

Run actions/deploy-pages@v1
  with:
    emit_telemetry: false
    token: ***
    timeout: 600000
    error_count: 10
    reporting_interval: 5000
    artifact_name: github-pages
    preview: false

This appears to still be broken, but I'm not sure why.

Alright, this definitely doesn't work! I reverted your change, but looks like I can't reopen this PR. Please open a new PR and we'll try to get to the bottom of this!

Thanks for bringing this action to my attention @nickmccurdy! I had no idea it was an option.

Left a comment on the configure-pages repo to see if we need to upstream something to get this working without any setup.
