arrow

GH-14872: [R] arrow returns wrong variable content when multiple group_by/summarise statements are used (#14905)

Reprex using CRAN arrow:

``` r
library(arrow, warn.conflicts = FALSE)
library(dplyr, warn.conflicts = FALSE)

mtcars |>
  arrow_table() |>
  select(mpg, cyl) |> 
  group_by(mpg, cyl) |>
  group_by(cyl, value = "foo") |>
  collect()
#> # A tibble: 32 × 4
#> # Groups:   cyl, value [3]
#>      mpg   cyl value `"foo"`
#>    <dbl> <dbl> <dbl> <chr>  
#>  1  21       6     6 foo    
#>  2  21       6     6 foo    
#>  3  22.8     4     4 foo    
#>  4  21.4     6     6 foo    
#>  5  18.7     8     8 foo    
#>  6  18.1     6     6 foo    
#>  7  14.3     8     8 foo    
#>  8  24.4     4     4 foo    
#>  9  22.8     4     4 foo    
#> 10  19.2     6     6 foo    
#> # … with 22 more rows
