feat: Support ESLint 7.x

[MichaelDeBoey]

ESLint v7.0.0 is released 🎉

(dev)Dependencies should be compatible with ESLint 7 too before we can merge this one:

• @mysticatea/eslint-plugin (Support ESLint 7.x mysticatea/eslint-plugin#28)
  • feat: support ESLint 7.x mysticatea/eslint-plugin#29
  • Release

---

Closes #70

[mysticatea]

Thank you for your contribution.

I have a question, why is the breaking change needed to support ESLint 7?

[MichaelDeBoey]

@mysticatea ESLint 7 only supports Node@^10.12.x || >=12.x
https://eslint.org/blog/2020/05/eslint-v7.0.0-released#dropping-support-for-node-js-v8
https://eslint.org/docs/user-guide/migrating-to-7.0.0#node-js-8-is-no-longer-supported

[mysticatea]

I know it because l have made that change. But, that is not requirements for custom parsers.

[MichaelDeBoey]

Then we would probably fix the test in some way, no? 🤔

[mysticatea]

Yes. We should not need breaking changes. Let's just confirm the parser works well on ESLint 7.

[MichaelDeBoey]

Hmmm really weird that CI keeps failing when I updated the tests 🤔🧐
Can't figure out what's causing the fails though.

[mysticatea]

I merged this along with some tweaks: 2df66e4

• Update git submodule /test/fixtures/eslint to ESLint 7
• Handle new syntax errors of the new minor version of acorn
• Convert bash script in CI to Node.js script for Windows job

Thank you.

@mysticatea Any idea when this will be released? 🤔
