Using `require.resolve("worker-loader")` to check if `worker-loader` is installed causes webpack to include `worker-loader` in the output bundle, which is not the intended effect. Aside from increasing the bundle size unnecessarily, it also causes errors for webpack configs with targets that don't have node's built-in modules.
These errors can be fixed by configuring webpack `externals` to exclude `worker-loader`, but it's more difficult to figure out this solution than to figure out that `worker-loader` needs to be installed (even without this explicit error message).
To solve this, the explicit check for `worker-loader` has been removed. An alternative solution would be to use webpack's `resolveWeak`. Documentation has also been added in `examples/webpack` to help users.
