Environment and package version

webpack: v4.x
html-inline-script-webpack-plugin: v1.1.5

Reproduction link / code sample

No need to actually run a build, just look at the code for index.js npm installs:

npm i html-inline-script-webpack-plugin@^1 -D
cat node_modules/html-inline-script-webpack-plugin/dist/index.js

Or download directly: https://registry.npmjs.org/html-inline-script-webpack-plugin/-/html-inline-script-webpack-plugin-1.1.5.tgz

What is expected?

It should not claim to be version 2 and should not claim that webpack 5 is required

What is actually happening?

It claims to be v2
