[Bug]: Unit test coverage is broken in CI

[IanVS]

Describe the bug

Currently seeing this in CI:

Failed to collect coverage from /tmp/storybook/code/frameworks/nextjs/src/next-image-loader-stub.ts
ERROR: /tmp/storybook/code/frameworks/nextjs/src/next-image-loader-stub.ts: `export =` is not supported by @babel/plugin-transform-typescript
Please consider using `export <value>;`.
  29 | nextImageLoaderStub.raw = true;
  30 |
> 31 | export = nextImageLoaderStub;

To Reproduce

Check a recent CI job

System

No response

Additional context

I tried changing to a default export, but then I get errors like this:
