Description
### Describe the enhancement requested
Arrow's R package build scripts use bash-specific syntax (`[[` test operator), requiring users to install bash on Alpine Linux (which uses `/bin/sh` by default). If we replace bash-specific syntax with POSIX sh equivalents, Arrow is buildable on Alpine without requiring bash installation; see #46769
