Container Image/Build does not consider Build Type in Dev UI

[ghost]

Describe the bug
If you want to build a Docker image via the Dev UI then a "Build Type" different to "Jar" ("Native", "Legacy Jar", "Mutable Jar") is not considered.

Expected behavior
The "Build Type" should be considered and a build for the desired type being triggered.

Actual behavior
It always builds an image with the following log entries:

2021-03-12 17:49:21,928 INFO  [io.qua.con.ima.doc.dep.DockerProcessor] (build-19) Building docker image for jar.                                                                                                  
2021-03-12 17:49:21,929 INFO  [io.qua.con.ima.doc.dep.DockerProcessor] (build-19) Executing the following command to build docker image: 'docker build -f /home/belu/git/quarkus-quickstarts/getting-started/src/main/docker/Dockerfile.jvm -t belu/getting-started:1.0.0-SNAPSHOT /home/belu/git/quarkus-quickstarts/getting-started'

To Reproduce

Steps to reproduce the behavior:

1. Use e.g. the Quarkus Quickstart project 'getting-started'
2. Add the following dependency: quarkus-container-image-docker
3. mvn clean quarkus:dev
4. Open Dev UI for Container Image/Build: http://localhost:8080/q/dev/io.quarkus.quarkus-container-image/build
5. Select "Build Type" different to "Jar", e.g. "Native"
6. Click "Build"
7. Verify in logfile that no Docker image with native runnable has been created.

Environment
