DevUI extension URL is not reachable in 2.x.x Quarkus (1.1 branch)

0. checout 1.1 branch. (now it is only living in the PR until it is not merged). Then do the steps from this https://github.com/vaadin/quarkus/pull/122,:
1. To build the extension locally: mvn clean install -Dvaadin.flow.version=23.3-SNAPSHOT

2. mvn io.quarkus.platform:quarkus-maven-plugin:2.16.7.Final:create \
   -DprojectGroupId=org.acme -DprojectArtifactId=getting-started \
   -Dextensions='com.vaadin:vaadin-quarkus:1.1-SNAPSHOT' -DwithCodestart \
   -DplatformVersion=2.16.7.Final -Ddata="vaadin-flow-codestart.vaadinVersion=23.3.12"

3. cd getting-started
4. execute the project with dev profile mvn quarkus:dev

The DevUI will not be reachable:

• http://localhost:8080/q/dev-ui/extensions on this URL:

Although main/master branch, Quarkus 3.x.x version, similar steps executed, and DevUI is reachable:

After some investigation with the help of @mcollovati (thanks). It seems the URL-s slightly modified for different Quarkus versions, which caused the confusion:

• Quarkus 3.x.x: http://localhost:8080/q/dev-ui/extensions
• Quarkus having devUI since 2.3.0: http://localhost:8080/q/dev/

There was no /extensions sub-path back then.

So the ticket is rather a document update to contain the proper URLs.

Also, there was some glow-up for the Quarkus 3, using Web components (Lit and Vaadin 🎉):

• https://github.com/quarkusio/quarkus/wiki/Dev-UI-v2

Old UI looks like this:

It was fixed by investigation and documenting it by the PR-s.
