add eslint-webpack-plugin to plugins list

[chenxsan]

CI for pull request #3963 failed now https://travis-ci.org/github/webpack/webpack.js.org/jobs/730802775#L992, it might be a result of the update here webpack-contrib/eslint-loader@fc94b5d because eslint-webpack-plugin is not existed yet in this repository.

BTW, it's wrong to edit the plugins.json or loaders.json file like this, they should be generated by src/utils/fetch-package-repos.js automatically. But let's fix that later after the webpack 5 branch get merged as there're already multiple manual edits as I found, e.g. #3985, #3903

It seems to be caused by this empty table head in eslint-webpack-plugin's readme:

cc @evilebottnawi Any chance we can fix it in eslint-webpack-plugin repository? Just add something non-empty like - should be enough. Otherwise we have to fix it in https://github.com/montogeek/remark-responsive-tables/blob/master/src/index.js#L20 with something like below to permit empty head:

headers = node.children.map(header => typeof header.children[0] !== 'undefined' ? header.children[0].value : '');

[chenxsan]

I've submitted a pull request to fix the empty head problem. But I think we have another choice here as we can remove the deprecated eslint-loader to work around the empty table head problem.

yes lets remove, maybe also stick a redirect on the loader page to plugin page?
