Downgrade eslint or update pi install docs?

[jedahan]

eslint v8 doesn't install on nodejs v12 which is the latest supported version for Raspberry Pi OS on the raspberry pi zero w.

I had to do the following to fix it, where should I put this info, or is there a major downside to downgrading if it expands hardware support?

npm remove eslint
npm install --save-dev eslint@7 strip-json-comments
