Fix cargo-generate arguments and binary URL

[michalvavra]

• Link to download cargo-generate binaries had incorrect URL
  • This caused an issue when cargo-generate was not installed in PATH (via cargo install cargo-generate)
• Arguments for cargo-generate
  • Missing generate argument (it's also needed when invoking the command from PATH ~/.cargo/bin/cargo-generate generate)
  • --name test should be send to ["--name", "test"]

Thanks for the PR. I'm deep into something else. I'll have a look at the latest Thursday.
