Description of changes

The whole design of this feature is heavily inspired by Vite. See InlineConfig, resolveconfig() and CLI

Improves CLI configuration with commander:

$ pnpm exec create-schemas --help

Usage: create-schemas [options] [input]

Options:
  -v, --version        display version number
  -c, --config <file>  use specified config file (default: "create-schemas.config")
  -i, --input <path>   path to the OpenAPI schema file
  -o, --output <path>  output file path (default: "openapi-types.ts")
  --cwd <path>         path to working directory (default: ".")
  -h, --help           display available CLI options

Add support for config file with c12:

// create-schemas.config.ts
import { defineConfig } from "@workleap/create-schemas";

export default defineConfig({
  input: "v1.yaml",
  output: "codegen/schema.ts",
  openApiTsOptions: {
    enum: true,
  },
});

User configuration is now validated with zod (feel free to bikeshed on the format of the message):

$ pnpm exec create-schemas -o out.ts

Invalid configuration:
 - input: Required
Use --help to see available options.

Breaking changes

The openapi-typescript command line arguments are no longer supported on the CLI. Instead, they need to be declared in the configuration file in the openApiTsOptions property.

Additional checks

As mentionned, still waiting for #8 and #9 to get merged. Once they are merged, I will update this PR to include a changeset and tests.
