Stencil: v16.7.0 Cannot use import statement outside a module

[finikwashere]

Describe the bug
Using version 16.7.0 (unreleased on npm, forked from the main branch) and the latest "@stencil/core": "^4.1.0".
I understand there are reasons why this was not published yet, but this issue could be a heads-up. Maybe my setup is wrong and imports are broken for some reason. I could appreciate your help.
While running build target on a stencil library with angular and react output targets, it fails to with an error:

> nx run stencil:build
 >  NX   Cannot use import statement outside a module

/node_modules/@nxext/stencil/src/executors/build/executor.ts:1
import { StencilBuildOptions } from './schema';
^^^^^^

To Reproduce

1. Create nx workspace@16.7.2 with @nx:angular and @nx:react apps and libs.
2. Add "@nxext/stencil": "https://gitpkg.now.sh/antonselukh/nx-extensions/packages/stencil?main", or directly from main branch of this repo
3. create a stencil lib
4. build it

Expected behavior
It should be able to import a schema json file, and cause no console errors.
