Webpack 5 gives peer dependency warning

[GaryB432]

Expected behaviour

Plugin should allow webpack 5 pre-releases peer dependency without warning

Current behaviour

npm install

npm WARN html-webpack-plugin@4.4.1 requires a peer of webpack@>=4.0.0 < 6.0.0 but none is installed. You must install peer dependencies yourself.

Environment

Node.js v12.18.2
win32 10.0.18362
npm 6.14.5
webpack@5.0.0-beta.29
html-webpack-plugin@4.4.1

Notes

I guess 5.0.0-beta.29 is indeed less than 6.0.0 but I wonder if the embedded spaces in your peerDependencies range specification is correct. Maybe we want webpack@>=4.0.0 <6.0.0

[GaryB432]

looks like other plugins are warning about, e.g., webpack@^4.37.0 || ^5.0.0 too. I am unsure about the prelease tag handling and why 5.0.0-beta.29 doesn't satisfy this range either.

ref Masterminds/semver#10 (comment)

It seems reasonable that the plugin would warn when webpack has a prerelease tag. But you still may want to remove your space or use the double-pipe specification as in my prior comment. Thanks for the great plugin!

Cool - can you please <create a pr?

Please avoid adding 5.0.0-beta.29 because when we something change in rc releases you need to keep compatibility with 5.0.0-beta.29 otherwise it will be breaking change
