docs: fix typo of publicAssetURL

[camerondubas]

Just noticed this example config didn't match the actual property name

I think this is still incorrect because it's showing publicAssetURL inside webpackConfig. publicAssetURL is an option to @embroider/webpack not to webpack.

ah, you're right! I updated the commit

I wonder if this was not refering to https://webpack.js.org/configuration/output/#outputpublicpath instead which is very similar in function

[ef4]

Yeah I wondered that too but I think the docs are better here if they show our publicAssetURL, not webpack's output.publicPath.

Thanks!
