Update Console's Webpack version to 5+

Update Console's webpack version to latest version (or at least 5)

If necessary are some dependencies that will need to be updated or hopefully removed:

•   ts-loader: May need to be updated to version9 or higher
•   cache-loader: Note that this is currently deprecated and recommends the use of webpack's caching options.  See: https://github.com/webpack-contrib/cache-loader
•  null-loader: Note that this is currently deprecated and recommends the use of webpack's resolve.alias.package setting.  See: https://github.com/webpack-contrib/null-loader
• html-webpack-plugin: The version in use is 3, but version 5 is recommended for Webpack 5. 

Note that an update of webpack depdencies is being addressed in CONSOLE-2972.   Changes from from that story should be done before starting on this story.
