sw.js file isn't created

[colenso]

Not sure if this is a bug or if I haven't configured it correctly. But the sw.js file isn't getting created when I run my project on localhost after installing this addon. I can see that it should be created as part of the postprocessTree hook call but this hook isn't getting called for some reason.
@josex2r or @adrigzr can you help me figure this out?

It would be helpful to note that my project uses embroider. Maybe that hook isn't being called when using embroider? Found a related issue: embroider-build/embroider#112
