Update version to 0.6.1 (#95)

0.6.1 release is purely to fix docs.rs build

Fix publishing (#84)

Fix publishing with cargo release

1. Fix version specifications for in-repo packages in workspace Cargo.toml
2. Don't release butane_test_helper
3. Don't specify version for butane_test_helper when referencing it. This allows butane_core to be published despite the circular dev-dependency. See rust-lang/cargo#7333

chore: Release butane version 0.6.0

chore: Release butane_cli version 0.6.0
