Bump webpack from 4.25.1 to 4.26.0 in /js

[dependabot-preview]

Bumps webpack from 4.25.1 to 4.26.0.

Release notes

Sourced from webpack's releases.

v4.26.0

Features

• Switch from uglify-es to terser as default minimizer

Note: While they are officially backward-compatible, it can still happen that a new bugs occurs with terser, which break your production builds. Make sure to validate your production builds after upgrading to this version. (Note that it's always a good idea to test your output assets before deploying.)

If you want to report bugs to terser (https://github.com/terser-js/terser), please provide a minimal repro case with minimized and non-minimized code. You can configure webpack to generate non-minimized code in production mode by setting optimization.minimize: false. When reporting a bug to terser, best report a repro case which doesn't require running webpack and is reproducible with only the terser command line.

See optimization.minimizers configuration option to switch back to uglify-es or provide additional minimize options for terser.
