Support ESLint 8.x

[MichaelDeBoey]

ESLint v8.0.0 is released 🎉

It would be awesome to have official ESLint 8 support. 👊
I'm happy to help where I can of course 🙂

@octogonz - want to take a look at this?

We don't normally adopt or support beta versions of tools (since it's already a nontrivial time investment to keep up with officially released versions 😇).

I'm fine however if someone wants to make a PR that enables usage of eslint-v8.0.0-beta-*. Heft should probably print a notice to the console saying it's not officially supported.

I'm also curious to see what will happen with @rushstack/eslint-patch.

Any updates or news from this issue?

@iclanton I think this should be reopened since #2965 only solved issues for eslint-patch package.
