Move `@types/eslint` to `devDependencies`?

[Arnaud Thomas D.]

Hello 👋

I'm having trouble in my app with ESLint typing because of "@types/eslint": "6.8.0" set as a dependency in SyncedStore (latest version of ESLint being 8.50.0 as of the writing of this issue).

Would it be possible to move it to devDependencies instead? Or is there a good reason that's not the case?

I can open a PR.

Thank you!
