Webjars-locator only works in quarkus:dev mode

[mejlholm]

Describe the bug
New extension quarkus-webjars-locator in 1.6.0.CR1 should be fairly straightforward to use. It works as expected in
quarkus:dev mode, but in a jar/docker container it doesn't seem to work (if I'm not missing something).

Reproducer can be found here:
https://github.com/mejlholm/webjars-locator-reproducer

Expected behavior
Web application on localhost:9080/index.html finds all webjar included dependencies without versions.

Actual behavior
404 - not found.

To Reproduce
Build and run jar/container.

Configuration
Nothing special.

Screenshots
In dev mode

In jar/docker container
