ESLint 8 support

[IlCallo]

Keeping track of eslint deps ESLint8 support status

TS ecosystem is nearly ready, JS is still lagging

Already support ESLint8 and safe/tested versions:

• eslint-plugin-vue -> 7.20.0
• eslint-plugin-import -> 2.25.1
• eslint-config-prettier -> 8.3.0
• @typescript-eslint/* -> 5.2.0

Support still missing:

• eslint-webpack-plugin: the support PR has already been merged yesterday, not released yet (https://github.com/webpack-contrib/eslint-webpack-plugin/pull/121)
• eslint-config-standard: work in progress (https://github.com/standard/eslint-config-standard/pull/193)
• eslint-plugin-node: should work, but there's some regressions (https://github.com/mysticatea/eslint-plugin-node/issues/294)
• eslint-plugin-promise: work in progress (https://github.com/xjamundx/eslint-plugin-promise/pull/219)
• eslint-config-airbnb-base: no support right now (https://github.com/airbnb/javascript/issues/2478)

I pinged eslint-plugin-node maintainer about this Otherwise we could rely on this fork: https://github.com/mysticatea/eslint-plugin-node/issues/294#issuecomment-996512961 It basically only adds ESLint 8 support, could be a good "bridge" until an official solution comes out
