(devel/R-devtools) Updated 2.3.2 to 2.4.1

# devtools 2.4.1

* `build_readme()` now uses the `path` argument, as designed (#2344)

* `create()` no longer opens projects by default to avoid duplicate projects opened by the RStudio IDE project template (#2347, @malcolmbarrett)

* The RStudio addins now use `test_active_file()` and `test_coverage_active_file()` instead of the deprecated `test_file()` and `test_coverage_file()` (#2339)

* RStudio addins now run in interactive mode, rather than background mode (@jennybc, #2350)

* `install(upgrade)` now defaults to 'default' rather than 'ask'. This allows you to control the default asking behavior with the `R_REMOTES_UPGRADE` environment variable (#2345)

# devtools 2.4.0

## Breaking changes and deprecated functions

* The `check_results()` function has been removed.
  It was not used by any CRAN package, and much better alternatives are available in the [rcmdcheck](https://github.com/r-lib/rcmdcheck) package.

* `pkgload::inst()` is no longer re-exported (#2218).

* `test_file()` has been renamed to  `test_active_file()` and `test_coverage_file()` has been renamed to `test_coverage_active_file()` to avoid a name collision with `testthat::test_file()`.
  The previous names have been soft deprecated in this release, they will be hard deprecated in the next release and eventually removed. (#2125)

## Re-licensing

* devtools is now released under a MIT license (#2326)

## Minor improvements and fixes

* `build_readme()` now supports readme files located in `inst/README.Rmd`, as intended (#2333)

* `build_vignettes()` now creates more specific `.gitignore` entries (@klmr, #2317)

* `check()` now only re-documents if you have a matching version of roxygen2 (#2263).

* `change_maintainer_email()` now has a check to assess whether the email is actually changed.
  If the email is not changed, the code now stops such that an email is not accidentally sent to the wrong recipient. (@emilsjoerup, #2073)

* `run_examples(fresh = TRUE)` again works without error (#2264)

* The covr and DT packages have been moved from Imports to Suggests.
  They are only needed when running `test_coverage()` and `test_coverage_active_file()` so now you'll be prompted to install them when needed.

* Switched to fs for all file system functions (#2331, @malcolmbarrett)

* Now uses testthat 3.0.0 to power `test()`, `test_active_file()`, `test_coverage()`, and `test_coverage_active_file()`.
  The major difference is that `test_active_file()` now generates a compact summary that takes up less space on the console.
