Default to `stable` when no active toolchain is present

[soloturn]

Problem

having cargo and rustup installed and call it first time it errors out, the only action i did not expect when building something. if you can print "run a command to choose stable" then really the software can choose a reasonable default by itself please. " you did not specify, so i chose ... for you".

❯ cargo build -p daemon --bin kanidmd --release
error: rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured.
help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain.
