@types/webpack throwing type errors in Webpack v5

imagemin-webpack-plugin has a dependency on @types/webpack v4. However, v4 imports tapable which in recent versions will break with webpack v4. This means that if you upgrade to Webpack v5 which will upgrade tapable internally, you end up with type errors coming from imagemin-webpack-plugin (unless skipLibCheck is set to true)

node_modules/imagemin-webpack-plugin/node_modules/@types/webpack/index.d.ts:32:3 - error TS2305: Module '"tapable"' has no exported member 'Tapable'.

And so on. I'm not positive what the right answer is here but maybe making @types/webpack a peerDependency or using * instead of v4 may fix it.
