breaks when no `exports` defined

a lot of typescript libs, e.g. almost all of @libp2p/*, seem to only contain exports like those:

  "exports": {
    ".": {
      "types": "./src/index.d.ts",
      "import": "./dist/src/index.js"
    },
  }

which breaks with the following example error from my project:

@parcel/core: Failed to resolve 'libp2p' from './src/index.js'

  > 1 | import { createLibp2p } from 'libp2p';
      |                              ^^^^^^^^

as you can see, i'm trying to actually do an ESM import, but require.resolve seems to either hard-depend on an actual CJS require entry there, which the lib doesn't support, or is too stupid to realize that yes, . is in fact "main"
