fix: add @types dependencies for tapable + webpack

Fix this error when using strict package managers like pnpm/yarn pnp:

    ERROR in /path/to/project/node_modules/.registry.npmjs.org/fork-ts-checker-webpack-plugin/1.2.0/node_modules/fork-ts-checker-webpack-plugin/lib/index.d.ts(1,26):

      Try `npm install @types/webpack` if it exists or add a new declaration (.d.ts) file containing `declare module 'webpack';`
