Conditional Rust tool-chain with Rust version

[kazuk]

I write coverage build make task.

https://github.com/kazuk/cargo-make-coverage-grcov

and, Rust 1.60 released.

Rust 1.60 have stable support for profile instrumentation.

so I needs switch tool-chain with project rust version. if grater 1.60 then Stable else Nightly.

some one knows how to do?

I found this example.

https://github.com/sagiegurari/cargo-make/blob/master/examples/toolchain.toml#L8

toolchain = { channel = "stable", min_version = "1.56" }

but this is failing build with toolchain condition not met.
