fix(webpack): assets should not be treaded as esModule

[mathis-m]

Description

loading /\.(png|jpg|jpeg|gif|svg)$/ relied on the default options of url-loader.
In one of the latest releases they swiched the esModule default from false to true.
https://github.com/webpack-contrib/url-loader/releases/tag/v3.0.0

switch to ES modules by default (the option esModule is true by default)

So in case of importing a asset with above stated types, it will be treated as esModule. This is why loading an svg resulted in [object%20Module].
To fix this I have edited the baseRules set to treat /\.(png|jpg|jpeg|gif|svg)$/ as no esModule.

Motivation and Context

Fixes #6850

@mathis-m Thanks for the fix! Fyi, I didn't mean to merge this dependency bump due to this config issue (fixed by this PR).
