Webpack 5 warning message conflict

[amirHosseinKhademii]

Please provide a description of the bug / issue, and provide the details below:

In webpack 5 after compilning webpack web dashbord replace all warning messages with custom messages but in new webpack release this messagse is type of object and not string therefore dev server would crash

Update: I've hit this in my current branch for webpack5 support and think I have a straightforward path to handle old + new webpack formats.

@sourena2575 Can you confirm that webpack-dashboard@3.3.0 has fixed the issue you've identified? Thanks!
