chore: use path library read_to_string for better error message (#6694) ### Description Noticed we were using the stdlib `read_to_string` instead of the one provided by `AbsoluteSystemPath`. The latter is better since it uses `fs_err` which includes the path in the error message. ### Testing Instructions 👀 Closes TURBO-1840 Co-authored-by: Chris Olszewski <Chris Olszewski>
