Chore: Move PublishConfig properties

[jackw]

I noticed you're making use of publishConfig to set package.json properties which is only supported by yarn berry and pnpm.

Given the package.json always points at dist there's no need to migrate to either of these package managers and we can move the properties out to allow consuming projects to make use of the esm builds.

Thanks for the reviews. I'm afraid I'm not familiar with this repo and cannot find any instructions on how versioning and publishing is handled. Could someone more familiar take over this PR to get the changes released please? 🙂

@jackw no problem, will release a new version today, thanks for the contribution!
