[hayawata3626]

Closed #311

Fixes by supporting import type syntax via useTypeImports option.

Settings

import {
  generateSchemaTypes,
  generateReactQueryComponents,
} from "@openapi-codegen/typescript";
import { defineConfig } from "@openapi-codegen/cli";

export default defineConfig({
  github: {
    from: {
      source: "url",
      url: "https://api.apis.guru/v2/specs/github.com/1.1.4/openapi.yaml",
    },
    outputDir: "src/github",
    to: async (context) => {
      const filenamePrefix = "github";
      const { schemasFiles } = await generateSchemaTypes(context, {
        filenamePrefix,
        useTypeImports: true,
      });
      await generateReactQueryComponents(context, {
        filenamePrefix,
        schemasFiles,
        useTypeImports: true,
      });
    },
  },
});

Hi! This PR adds a useTypeImports option to address the issue discussed in #311.
I'd appreciate it if you could take a look when you have a moment 🙏 Thanks for maintaining this great tool!

This looks amazing! So amazing that I think we should use this implem as default and bump the major version😀

I found some other parts that needed to be fixed, so I addressed those and enabled useTypeImports by default. Please check again!
