Improve monorepo documentation on dependencies

[atoiv]

Problem

In order to use storybook-deployer in a monorepo, you need to have the command build-storybook available in the monorepo root. It seems to come with @storybook/react and other storybook target libraries.

In a monorepo, you might have this dependency only available in a specific package where you use monorepo, and not in the monorepo root, where you run storybook-deployer.

Solution

List dependencies, at least under "Deploy a Monorepo" section, and explain in which package(s) the required command build-storybook comes.

It probably wouldn't hurt if there would be a list of required peer dependencies mentioned next to the installation instructions.

@atoiv I'm assuming you got this working? Could you share an example setup so I can get publishing working in my monorepo too?
