Bug#1007768: webpack 5 incompatible with eslint-scope >= 7

[Yadd]

Package: webpack
Version: 4.43.0-7
Severity: important

Hi,

in lib/optimize/ConcatenatedModule.js, webpack tries to use
eslint-scope/lib/referencer which is no more authorized in
eslint-scope/package.json#exports.

Here is an untested patch.

Cheers,
Yadd
