v1.0.4

• Removed validation for the toolchain input. The dtolnay/rust-toolchain accepts a lot of different options that this action wasn't allowing. It's simpler and more flexible to just let that action handle validation. Requested by @axos88 (Akos Vandra-Meyer). GH #42.
• Removed validation for the command input. This allows you to use this action with any cargo extension command, like cargo-deb. Setting command to both is still supported and will run the build and test commands. Requested by @bvaisvil (Benjamin Vaisvil). GH #43.
