URL: https://github.com/apache/arrow/issues/37762
### Describe the bug, including details regarding any error messages,
version, and platform.
The following fails
```
library(arrow)
library(dplyr)
write.csv(sleep, "sleep.csv", row.names = TRUE)
open_dataset("sleep.csv", format = "csv") |>
mutate(group = group + 1) |>
collect()
# Error in env_bind0(env, data) : attempt to use zero-length variable name
```
This is due to the first column having no column name.
```
open_dataset("sleep.csv", format = "csv") |>
head() |>
collect()
# A tibble: 6 × 4
`` extra group ID
<int> <dbl> <int> <int>
1 1 0.7 1 1
2 2 -1.6 1 2
```
