Bump webpack-dev-server from 2.9.3 to 3.1.3

[dependabot-preview]

Bumps webpack-dev-server from 2.9.3 to 3.1.3.

Release notes

Sourced from webpack-dev-server's releases.

v3.1.3

• Fix HMR causing a crash when trying to reload

v3.1.2

• Speed up incremental builds (#1362)
• Update webpack-dev-middleware to 3.1.2

v3.1.1

• Update to webpack-dev-middleware v3, which removes the deprecation warnings from webpack.

v3.1.0

Updates

• Fancy logging; webpack-log is now used for logging to the terminal (webpack-dev-middleware was already using this).
• The logLevel option is added for more fine-grained control over the logging.

Bugfixes

• MultiCompiler was broken with webpack 4.
• Fix deprecation warnings caused by webpack 4. Note that you will still see some deprecation warnings because webpack-dev-middleware has not been updated yet.

v3.0.0

Updates

• Breaking change: webpack v4 is now supported. Older versions of webpack are not supported.
• Breaking change: drops support for Node.js v4, going forward we only support v6+ (same as webpack).
• webpack-dev-middleware updated to v2 (see changes).

Bugfixes

• After starting webpack-dev-server with an error in your code, it would not reload the page after fixing that error (#1317).
• DynamicEntryPlugin is now supported correctly (#1319).

Huge thanks to all the contributors!

Please note that webpack-serve will eventually be the successor of webpack-dev-server. The core features already work so if you're brave enough give it a try!

v3.0.0-beta.2

• Since webpack v4 the entry option is optional and will default to ./src/. This didn't work in webpack-dev-server (#1308).

v3.0.0-beta.1

This beta release differs a lot with the earlier alpha versions.

The previous alpha versions dropped a lot of features and supported less browsers, in an effort to get webpack-dev-server back to its core.
These efforts have been moved to webpack-serve, and instead this major version of webpack-dev-version will focus on webpack v4 compatibility.

The changelog below is compared to the latest v2 version of webpack-dev-server:

• Support for webpack v4.
• webpack-dev-middleware updated to v2 (see changes).
