Update instructions for subproject site requests
Update instructions for subproject site requests

- Moves adding a `netlify.toml` at the root of the repo to the beginning
of the process, so that the site can be viewed directly once Netlify is
configured.

- Add a note about "Basic Build Settings" getting autopopulated with values
in netlify.toml.

- Remove step about explicitly enabling HTTPS. Netlify enables HTTPS
automatically after DNS records are updated.

- Some markdown improvements.
