Types aren't correctly exported for CJS

[Oupsla]

Description

Typescript with "moduleResolution": "node16" will generate an error when trying to import the module from a cjs file.

Could not find a declaration file for module 'openapi-typescript'. '/node_modules/openapi-typescript/dist/index.cjs' implicitly has an 'any' type.
  Try `npm i --save-dev @types/openapi-typescript` if it exists or add a new declaration (.d.ts) file containing `declare module 'openapi-typescript';`ts(7016)

Name	Version
openapi-typescript	7.4.4
Node.js	22.9.0
