fork-ts-checker-webpack-plugin use webpack (peer dependency) imply that webpack is auto installed by package manager as transitive peer depenedncy. All transitive peer dependencies must be used as dependencies or peer dependencies. An article written by author of yarn package manager: Implicit Transitive Peer Dependencies

webpack can be added once because it's a peer dependency.

Maybe fork-ts-checker-webpack-plugin should use webpack as @electron-forge/plugin-webpack:

// packages/template/webpack-typescript/package.json and packages/template/webpack-typescript/tmpl/package.json
"devDependencies": {
  "webpack": "npm:@electron-forge/plugin-webpack@^7.4.0"
}

Hey @rtritto, thanks for submitting a change, but I think we're going to reserve dependency changes to maintainers only. Thanks!
