The default resources layer currently gets its content from the following locations:
META-INF/resources/resourcesstaticpublic
I think it makes sense to add templates to this list as they're likely to change at the same frequency as content in the locations above. This would also align things more closely with the locations the do not trigger a DevTools restart but do trigger a live reload.

We can close this as we're going to go with a single layer for the application by default. See #20562.
