Using `docs` subdirectory to publish to gh-pages

[adisarid]

The blogdown book states there are two ways to deploy to github pages.

blogdown/docs/03-deploy.Rmd

Line 73 in e40271a

And the structure looks like this:

Either make the publish directory the repository for username.github.io or have a source directory.

I think that the following is preferable to both, and should be suggested as the main option (if using gh-pages) in the book:
Have the complete repo called username.github.io
Publish to a subdirectory called docs.
Add the .nojekyll file to docs.
Setup under settings->pages->Branch: main /docs
I.e. (here it says master since it's an old repo),
