fix: Ignores hot update files when generating the manifest

[michael-s-molina]

SUMMARY

Fixes the following error when running Superset with hot update enabled:

This happens because the manifest file was being generated with [hash].hot-update.js files. This PR adds a filter to the Webpack config to ignore these files.
