hdiutil is deprecated in macOS 27 Golden Gate

Apple's macOS 27 Golden Gate beta deprecates hdiutil, the traditional command-line tool for manipulating disk images. The man page states: "In macOS 27.0, hdiutil is deprecated. Use diskutil image instead for all disk image operations." diskutil image provides subcommands for attach, create, resize, info, and chpass, and is the only tool that supports ASIF (Apple Sparse Image Format) images. A deprecation notice lists replacements for hdiutil subcommands, though many options are renamed or missing.
