Contributor's fork must be named incubator-kie-kogito-images or PR checks won't work

[ricardozanini]

There's a bug in our Build & Test pipeline where the script is expecting the fork's to be named incubator-kie-kogito-images:

Cloning the remote Git repository
Cloning repository https://github.com/wmedvede/incubator-kie-kogito-images.git

ERROR: Error cloning remote repo 'origin'
hudson.plugins.git.GitException: Command "git fetch --tags --force --progress -- https://github.com/wmedvede/incubator-kie-kogito-images.git +refs/heads/*:refs/remotes/origin/*" returned status code 128:

stderr: remote: Repository not found.
fatal: repository 'https://github.com/wmedvede/incubator-kie-kogito-images.git/' not found

We should use the build parameters instead where we have the actual fork information.
