No info about making a folder and unboxing into it

[BboyAkers]

When unboxing a boilerplate. The initial assumption is that it'll unbox into a folder that is generated via the command 'npx truffle unbox kaleido-io/drizzle-kaleido-box' or 'truffle unbox kaleido-io/drizzle-kaleido-box'. The default behavior is otherwise by simply unboxing it into the current folder. Having documentation that states creating a new folder and unboxing into that would be ideal!
