single author and empty affiliation errors

[CarloLucibello]

The documentation mentions that for a single author one should use an empty affiliation identifier:

#show: elsearticle.with(
  authors: ((name: "Carlo Lucibello", affiliations: ("",)),),
  affiliations: ("": "Bocconi University, Milan, Italy",)
)

but this errors with

type none has no method `join`

Actually, you have to type (note the blank space):

#show: elsearticle.with(
  authors: ((name: "Carlo Lucibello", affiliations: (" ",)),),
  affiliations: (" ": "Bocconi University, Milan, Italy",)
)

I will correct this in the next release of the template.
