Webpack 5 support

[fwh1990]

As we know wepback@5 had been published some days ago, I hope that you can update error-overlay-webpack-plugin to compatible with latest webpack, thank you

Not a surprise! I will not fix it on my own, if someone is interested, feel free to submit a PR.

for whatever it's worth I just went ahead and installed error-overlay-webpack-plugin in a local repo and it appears to be working fine there despite the warning yarn showed upon installing. If chalk getting introduced into the browser by a dependency was the only problem this seems to be fixed now.
