What changes are included in this PR?

The key change is adding unset LD_LIBRARY_PATH before the macOS troubleshooting section. This ensures that when R loads the package, it uses the libarrow built from the git checkout (which matches the R package build), not the released version from apt.

This approach:
Still tests the troubleshooting documentation as intended
Prevents the ABI mismatch by ensuring the R package uses the libarrow it was built against
Works during the release gap when git checkout and released versions differ

Are these changes tested?

No

🤖 : Close as superseded: #49381 (vanshaj2023) fixed GH-49380 by removing the hidden CI chunks from setup.Rmd and is merged. Context: Adds unset LD_LIBRARY_PATH to the R developer setup vignette to work around the r-devdocs ABI mismatch; a different, merged fix removed the test chunks entirely.
