Ensure plugin types are exposed

[johannschopplich]

          This did not fix the problem. I tried updating the module to v1.0.1 and replacing `trackLocalhost` with `ignoredHostnames`, and all of the analytics e2e tests failed, see [this CI run](https://github.com/WordPress/openverse/actions/runs/10250122171/job/28355208871?pr=4716). When I added `trackLocalhost` back, they [passed](https://github.com/WordPress/openverse/actions/runs/10260245561/job/28386045331?pr=4716).

After updating, the plugin types also broke: I had to manually add the types that were previously created by Nuxt automatically. This might be related to the "The inferred type of 'default' cannot be named without a reference to ..." warnings in the release action run for v1.0.1: https://github.com/nuxt-modules/plausible/actions/runs/10229250370
Would using a function for module defaults fix it?
