Bug#1004471: Pending patch for terser-webpack-plugin in webpack 5 till a new upstream for node-terser is uploaded

[Caleb Adepitan]

Hi,

I just arrived at a working patch for terser-webpack-plugin to circumvent 
breaking changes in node-terser 5 which is required by the package. The 
available version of node-terser in debian is 4 which is behind the terser 
package upstream.

This patch is an ad-hoc fix for the bug pending the node-terser package is 
updated to a compatible version.

Here is the proposed patch:
