Should code chunk output use the `lang` config setting?

[Bisaloo]

Currently, lessons in another language than English use English for the code chunk output.

You can see an example in the https://github.com/swcarpentry/r-novice-gapminder-es lesson:

https://github.com/swcarpentry/r-novice-gapminder-es/blob/e4735e1d6e735a222d24b6a4fb9cc776fda096f0/06-data-subsetting.md?plain=1#L220-L222

Yet, in this situation, R is able to return the error message in Spanish, provided the LANGUAGE env var is set to es:

withr::with_language(
  "es",
  letters[-1:3]
)
#> Error in letters[-1:3]: solamente 0's pueden ser mezclados con subscritos negativos

Should sandpaper by default pick up the lang config setting and use it for the code chunk output?

I guess it mostly depends on which language users are expected to use in their system or IDE.

I'm not completely sure if this is only relevant for the R lessons, or all lessons.
