title: R blogdown::serve_site() doesn't generate "public" folder when using Hugo "gesquive/slate" theme
body: <p>I am trying to create a new blogdown project, and I've been using Yihui Xie's <a href="https://bookdown.org/yihui/blogdown/" rel="nofollow noreferrer">wonderful documentation</a> to get started.</p>
  
  <p><strong>This works as expected:</strong><br>
  Wen I run the below code, I see a live representation of the <a href="https://academic-demo.netlify.com/" rel="nofollow noreferrer">demo page</a>, and the <code>public</code> folder is generated in my local directory.</p>
  
  <pre><code>library(blogdown)
  blogdown::new_site(theme = "gcushen/hugo-academic")
  blogdown::build_site()
  blogdown::serve_site()
  </code></pre>

  <p><strong>This does not work as expected:</strong><br>
  But when I re-run using the  "gesquive/slate" theme, I see a live representation of the <a href="https://gesquive.github.io/hugo-slate-demo/" rel="nofollow noreferrer">demo page</a> as expected, but no <code>public</code> folder is generated in my local directory.  Without a <code>public</code> folder, I have nothing to send to Netlify.</p>
  
  <pre><code>library(blogdown)
  blogdown::new_site(theme = "gesquive/slate")
  blogdown::build_site()
  blogdown::serve_site()
  </code></pre>

  <p><strong>Why is a <code>public</code> folder generated when I use any Hugo theme other than "gesquive/slate"?</strong></p>
  
  <p>I expect that I'm misunderstanding something about how the package works with Hugo.</p>
