Fix asset size validation #470
Description
presently we are using the same numbers for:
- https://webpack.js.org/configuration/performance/#performancemaxassetsize
- https://webpack.js.org/configuration/performance/#performancemaxentrypointsize
I think that makes no sense. The way I see it we only need to worry about maxAssetSize, but maybe I'm wrong. Either way it makes no sense to use the same values for both.
