Custom Webpack config not supported with ES Modules

[MichaelGoberling]

Expected Behaviour

• Custom Webpack configuration can be provided for a project using ES Modules.

Actual Behaviour

➜  sequence_test git:(main) ✗ aio app run --local
ℹ checking if java is installed...
ℹ checking if docker is installed...
ℹ checking if docker is running...
ℹ starting local OpenWhisk stack...
ℹ writing credentials to tmp wskdebug config '/Users/mgoberling/repos/adobe/my-utils/utils/sequence_test/dist/application/.env.local'
ℹ building actions..
 ›   Error: require() of ES Module /Users/mgoberling/repos/adobe/my-utils/utils/sequence_test/actions/first/webpack-config.js from 
 ›   /usr/local/lib/node_modules/@adobe/aio-cli/node_modules/@adobe/aio-lib-runtime/src/build-actions.js not supported.
 ›   Instead change the require of webpack-config.js in /usr/local/lib/node_modules/@adobe/aio-cli/node_modules/@adobe/aio-lib-runtime/src/build-actions.js to a dynamic 
 ›   import() which is available in all CommonJS modules.

Steps to Reproduce

• aio app init with action
• Add webpack-configuration.js to your action folder
• Add "type": "module" to project package.json
• Run aio app run --local
• See error above

Additional notes

Due to import when building actions here
