build: update list size test golden to reflect latest changes

The list size test is currently slightly deviating from the golden.
This is unrelated to the TypeScript 3.9.5 update, but just came to time
as part of checking for any other size impact due to the TS update.

For reference: here is the build for the latest commit in `master`
at time of writing:
https://app.circleci.com/pipelines/github/angular/components/8713/workflows/61de1ab2-af77-4d73-86ce-f3dcd4f95143/jobs/151345/steps.

To inspect the actual size, open the streamed build results and inspect
the log output from the `size:nav-list` target.

```
Expected: 153231, but got: 153439
```
