[R] `wslify_path` breaks on windows in `create_package_with_all_dependencies`

### Describe the bug, including details regarding any error messages, version, and platform.

Hello,

First, thanks for this great function and ecosystem. It saved me a lot of headaches and work! :)

I am trying to get all the dependencies for the R package and I am using the function `create_package_with_all_dependencies`. However, it throws an error on my system:

``` r
arrow::create_package_with_all_dependencies()
#> Downloading Arrow source file
#> Warning in system2("bash", c(download_dependencies_sh, download_dir), stdout =
#> download_script, : Exit code was 127
#> Error in arrow::create_package_with_all_dependencies(): Failed to parse versions.txt; view C:\Users\lauerm\AppData\Local\Temp\RtmpYdNYVl\filec85a851e9c.R for more information
```

^{Created on 2024-10-17 with [reprex v2.1.1](https://reprex.tidyverse.org)}

Now after some investigation, it is caused by the `wslify_path` here:

https://github.com/apache/arrow/blob/1a323fc91bbbce2f231262a1619d5f15e9cb7762/r/R/install-arrow.R#L218-L220

If I copy the whole function body, and remove these three lines, all works as expected. I reckon it's an issue on my end and simply 'deleting' these three lines won't fix it.

I would be happy to create a PR that fixes this if you have any idea what might cause this. I have WLS installed, but I don't have any distros.

Thanks!
