(devel/R-withr) Update 2.4.1 to 2.4.2

# withr 2.4.2
- `local_options()` now lets you set an option to `NULL` as intended (#156)

- `local_tempfile()` argument `envir` is deprecated, in favor of
  `.local_envir`.  All withr functions except `local_tempfile()` used
  `.local_envir` to specify environments, so this makes this function
  consistent with the rest. (#157)

- `with_environment()` now passing `pos` and `warn.conflicts` to
  `attach()`, as intended (#161).

- `with_seed()` now also sets the RNG via new arguments `.rng_kind`,
  `.rng_normal_kind` and `.rng_sample_kind` (#162, @AshesITR).

- `with_timezone()` now works after recent changes to `Sys.timezone()`
  in R-devel (#165)
