Changes in version 2022-04-04                      

  - Moved rstantools from "suggests" to "imports"
  - Updated all packages
  - Received an error: "Files in the 'vignettes' directory but no files
    in 'inst/doc'". The solution was to run pkgdown::build_site(),
    delete /docs directory, and move the /doc directory to /inst.
