[Fix] Example node-app Arrow Errors

[tpulmano]

Trying to run the node-app example fails with import errors like this:

ERROR in ./node_modules/apache-arrow/ipc/metadata/message.mjs 46:14-33
Can't import the named export 'Builder' from non EcmaScript module (only default export is available)
 @ ./node_modules/apache-arrow/Arrow.mjs
 @ ./node_modules/apache-arrow/Arrow.dom.mjs
 @ ./node_modules/@kepler.gl/utils/dist/arrow-data-container.js
 @ ./node_modules/@kepler.gl/utils/dist/index.js
 @ ./node_modules/@kepler.gl/components/dist/side-panel/layer-panel/layer-list.js
 @ ./node_modules/@kepler.gl/components/dist/index.js
 @ ./src/app.js
 @ ./src/main.js

Copying this fix from the demo-app resolves them:

kepler.gl/examples/demo-app/webpack.config.js

Lines 40 to 45 in f897057

	// fix for arrow-related errors
	{
	test: /\.mjs$/,
	include: /node_modules/,
	type: 'javascript/auto'
	}
