use trpc-cli with peerDependencies

[mmkal]

Description

draft, using pkg-pr-new until a real vesrion is published

Just trying out mmkal/trpc-cli#146 - I want to stop bundling zod+trpc in trpc-cli. It's a good thing for you because there will no longer be an unnecessary version of zod in node_modules (tradeoff is that you have to add @trpc/server to package.json and import separately, but that's about it). Should make bundling CLIs less error-prone too - no more eval hacks.
