Support ESM

[PabloSzx]

graphql-middleware should support ESM 👍, especially since it will be kept for the next version of graphql-yoga

The recent blog post where I talked about it: https://the-guild.dev/blog/support-nodejs-esm

• Using bob-esbuild that uses rollup + esbuild
• Simple conversion from yarn to pnpm, specially needed for publishConfig.directory, check TypeScript > support for exports in blog post, since this library is not using changesets, which also supports it
