Update eslint-plugin-import

2.28.0 introduced a breaking change to `import/order` 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][1] by adding a second nested group with most if
not all of the other import types we use

It looks like #141
brought us back to 2.27.5. If we go back to 2.28.0 now and revert to
the simpler config, for some reason the ESLint errors don't reappear

In any case, I submitted a [bug fix][2] in eslint-plugin-import 💅
This was released in 2.28.1, so we should upgrade, hopefully preventing
an unexpected return to confusing errors
