In this branch(5.1) the most recent available rustc version is 1.60, despite that, the 'cargo install' command tries to install the most recent version of a package by default, which may rely on newer rustc versions. This patch specifies the version of the cxxbridge-cmd package to one that works with rustc 1.60. Closes scylladb/scylladb#15812 [avi: regenerated frozen toolchain] Closes scylladb/scylladb#15828
