Set language to english in local_reproducible_output()

[olivroy]

Addresses #1619.

Probably need to find a better way to respect language set in DESCRIPTION, any way to access this?

Similar to the approach in #1621

[IndrajeetPatil]

Something like this?

setwd("/Users/indrajeetpatil/Documents/GitHub/lintr")
desc::desc_get("Language")
#> Language 
#>  "en-US"

setwd("/Users/indrajeetpatil/Documents/GitHub/styler")
desc::desc_get("Language")
#> Language 
#>       NA
