autofixing "no-duplicates" does not add whitespace after commas

[resolritter]

I had some code like this

import { a } from "pkg"
import { b } from "pkg"

ESLint's autofix for "import/no-duplicates" did work, but it left a and b glued together like so

import { a,b } from "pkg"

Having the imports glued by commas upsets Prettier. A sensible solution is to add a whitespace after the comma(s).

import { a, b } from "pkg"

It seems that setting up eslint-plugin-prettier gets around this... But it'd be nice if this plugin could add the whitespaces by itself

prettier should only ever be run via eslint anyways :-)

an alternative solution is to use the comma-spacing eslint rule to correct it. I’d be fine changing this rule to add the whitespaces by default tho, since that’s by far the more common style.
