Possibly outdated instruction in Chapter 20: Packages, Subsection: Deploying your app-package

[david-vicente]

Since rsconnect recursively detects all R package dependencies for an application by parsing all .R and .Rmd files, is it really necessary to add pkgload to the list of Imports here:

• Normally when you deploy an app, the rsconnect package automatically figures out all of the packages your code uses.
  But now that you have a DESCRIPTION file, it requires you to explicitly specify them.
  The easiest way to do this is to call usethis::use_package().
  You'll need to start with shiny and pkgload:

 usethis::use_package("shiny")
 usethis::use_package("pkgload")
 ```

source, web?

I tested on Shinyapps.io without putting pkgload in the DESCRIPTION file and it worked.
