CLI's package.json missing script to auto-install dependencies after CLI installation

Describe the bug
After running npm install -g @stacks/cli, I tried using the stx command which failed with this error message:

internal/modules/cjs/loader.js:803
    throw err;
    ^

Error: Cannot find module 'typescript

I had to manually run npm i inside the CLI package to resolve the error.

There are two one possible solution:

1. add typescript to @stacks/cli dependencies:

You'll need to install typescript locally since v8, it's using require.resolve which has its own separate limitations but is used to resolve a different issue. That means typescript is resolved from where you're running it right now.

See: TypeStrong/ts-node#707 (comment)

2. bump ts-node to 9.y.z

This is most likely the way to go, but I have to check that everything still works after a major version bump.

I'm working on this

ts-node has typescript as a peerDependency, and peer dependencies are not installed by default from NPM v3-v6. NPM 7 reintroduced the automatic installation of peer dependencies.

The issue is no longer present on the latest NPM version. To fix it for those using older versions of NPM, listing typescript as a dependency is the only solution.
