feat(#354 | create-hypergraph-app): move hypergraph-app-template into hypergraph monorepo

[cmwhited]

Description

This is the initial PR to build a "create hypergraph-app" CLI tool. Moving the hypergraph-app-template into a "template-*" structure inside of the "create-hypergraph-app" package. This way, the templates will ship with the create hypergraph-app cli tool and when the user selects a template (just vite + react) to start, it can pull the code from the tool internally, instead of needing to perform either a git clone (like the hypergraph-cli does currently) or fetching the git archive.

I used create vite app as a reference, and this is how they built their create vite app cli tool.

In the future we can add template-nextjs, template-vite-vue, etc templates to give the user choices. of which template to scaffold.

Next PR will be to build out the create hypergraph-app cli tool

Reference #348

Closes #354

I would like to add more to this about how to interact with the schema.ts file/hypergraph. Will think on it. Will also add notes on using the typesync studio, once it is ready

good idea 👍

Need to replace this with import type { Mapping } from '@graphprotocol/typesync/Mapping';, but requires updates to hypergraph and hypergraph-react. See this PR as the packages will need to be published to npm
