Type error: Re-exporting a type when the '--isolatedModules' flag is provided requires using 'export type'

See original GitHub issue

Hi! 👋

Firstly, thanks for your work on this project! 🙂

I got this error from typescript while creating build version of nextjs. ( I am using 5.5.1 version of ethers on Ubuntu 20.04 LTS )

npm run build

> build
> next build

./node_modules/ethers/src.ts/ethers.ts:96:5
Type error: Re-exporting a type when the '--isolatedModules' flag is provided requires using 'export type'.

And here is the diff that solved my problem:
