Update eslint-plugin-import

2.28.0 introduced a breaking change where the order of nested groups
(whose purpose is to define different types of imports that are of
equivalent rank) started to matter: a single nested group would be
treated as though it wasn't nested

We got around this by adding a second nested group with most if not all
of the other import types we use

I [fixed the bug][1] in eslint-plugin-import 💅🏻 and this was released in
2.28.1, so we can now revert to the simpler config post-upgrade

[1]: import-js/eslint-plugin-import#2854
