(devel/R-usethis) Updated 2.2.0 to 2.2.2

# usethis 2.2.2

* Implicit usage of `numeric_version()` via comparison now always provides
  character input. This is in response to a request from CRAN to anticipate
  future solutions to <https://bugs.r-project.org/show_bug.cgi?id=18548>.

# usethis 2.2.1

* Internal helper `cran_version()`, used in functions such as
  `use_release_checklist()` and `use_news_md()`, is more resilient to situations
  where no CRAN mirror has been set (#1857).

* Internal usage of `numeric_version()` now always provides character input,
  rather than relying on implicit `as.character()` coercion. This is in response
  to a request from CRAN to anticipate future solutions to
  <https://bugs.r-project.org/show_bug.cgi?id=18548> (#1869).
