Migration to webpack5 as test are failing

[AyoyimikaAjibade]

Please update your package to migrate to webpack5 as maintaining it in the Debian OS environment produces failing test as we try to build the package with webpack 5.65.0, while the support of webpack3 is deprecated here is a link to the bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1001629

The failing test output looks like this while building with webpack 5.65.0

+ mocha -R spec --timeout=30000


  StatsWebpackPlugin
    1) generates `stats.json` file
    2) supports multi-compile mode and outputs one `stats.json` file
