fix(zod-validator): resolve module support issue in Zod validators

[mofareedd]

Description:
When importing @hono/zod-validator in a ESM environment, the following error occurs:

The current file is a CommonJS module whose imports will produce 'require' calls;
however, the referenced file is an ECMAScript module and cannot be imported with 'require'.

This issue arises because the CommonJS and ESM entry points in the package are not correctly configured in package.json. This misconfiguration causes compatibility issues when the library is used in different module systems.

This PR resolves the compatibility issue by updating the entry points in package.json:

• Set the CommonJS entry point to dist/index.js
• Set the ESM entry point to dist/index.mjs

package.json

{
  "main": "dist/index.js",
  "module": "dist/index.mjs",
}

Hi @mofareedd

The current setting may be correct. It does not create dist/index.mjs for ESM but creates dist/index.js as ESM and dist/index.cjs as CommonJS:

yusuke $ ls -l dist
-rw-r--r--@ 1 yusuke  staff  1698 12  5 17:01 index.cjs
-rw-r--r--@ 1 yusuke  staff  1252 12  5 17:01 index.d.cts
-rw-r--r--@ 1 yusuke  staff  1252 12  5 17:01 index.d.ts
-rw-r--r--@ 1 yusuke  staff   666 12  5 17:01 index.js

Can you confirm again that your project is correct?
