feat(cli): monorepo changes required to run create-catalyst CLI

[matthewvolk]

What/Why?

• References to cn in Reactant must be through tsconfig paths. This allows components to be copied over into apps/core without needing to modify cn references.
• Adds dotenv-cli to apps/core so that codegen and dev-codegen package scripts can be run outside of the monorepo.
• Add tsconfig path in apps/core to map references to @bigcommerce/reactant/* to ./node_modules/@bigcommerce/reactant/*. When the create-catalyst CLI creates the new project tsconfig, this path is mapped to ./components/ui/* where the Reactant components are copied into.
• Similarly, add tsconfig path in packages/reactant to allow references to cn inside packages/reactant to be the same as references to cn from within apps/core.
• apps/core/userAgent.ts cannot reference monorepo package.json outside of the monorepo.
• Reconcile differences between packages/reactant/.eslintrc.cjs and apps/core/.eslintrc.cjs so that we can have a single .eslintrc.cjs to use while Catalyst is running outside of the monorepo.
• Reconcile differences between packages/reactant/tailwind.config.js and apps/core/tailwind.config.js so that we can have a single tailwind.config.js to use while Catalyst is running outside of the monorepo.

Without this, building storybook crashes with an error:

Error: [vite]: Rollup failed to resolve import "~/lib/utils" from "catalyst/packages/reactant/src/components/Input/Input.tsx".
