(devel/R-roxygen2) Updated 7.1.1 to 7.1.2

# roxygen2 7.1.2

* The new `@examplesIf` tag can be used to create conditional
  examples. These examples only run if a specified condition
  holds (#962).

* roxygen2 is now licensed as MIT (#1163).

* Bug fix for upcoming stringr 2.0.0 release.

* Code blocks with language now add `sourceCode` to the generated div; this
  makes syntax highlighting more consistent across downlit/pandoc/knitr/roxygen2.

* Percent signs in markdown link targets, e.g. `[text](https://foo/ba%20r)`
  are now handled correctly (#1209).
