fix: revert dynamic import of webpack config file

[ZachJW34]

User facing changelog

n/a

Additional details

This PR reverts the change made to webpack-dev-server for how we are loading the sourced webpack.config.{js,ts}. Previously it was using loadModule which is basically a require. We changed it to use a dynamic import but this no longer works when doing await import('{project-root}/webpack.config.ts') as ts-node does not process the typescript webpack config file.

No user-facing change as the dynamic import was never published.

Steps to test

On develop, run yarn cypress:open and choose an app that has a webpack.config.ts and does not specify it in the cypress.config.ts. svelte-webpack-ts is a good example. This will fail.

Checkout this branch and run yarn. Run the same steps above and the app will load.

How has the user experience changed?
