[10.0.x] CI duplicate maven configuration entries

[jstastny-cz]

Adjusting branch.yaml configuration to split maven related configurations for nightly and release.

Part of ensemble:

• [10.0.x] CI duplicate maven configuration entries incubator-kie-kogito-pipelines#1254
• [10.0.x] CI duplicate maven configuration entries incubator-kie-drools#6130
• [10.0.x] CI duplicate maven configuration entries #3133
• [10.0.x] CI duplicate maven configuration entries incubator-kie-optaplanner-quickstarts#634
• [10.0.x] CI duplicate maven configuration entries incubator-kie-kogito-runtimes#3737
• [10.0.x] CI duplicate maven configuration entries incubator-kie-kogito-apps#2119
• [10.0.x] CI duplicate maven configuration entries incubator-kie-kogito-examples#2025

The scope of changes:

• maven settings.xml reference (config file id pointing at pre-defined config file in jenkins)
• artifacts upload repository
  • url - mostly informational, should not be needed for deploy itself (inheriting that configuration from apache parent)
  • credentials-id - the important part, allowing to configure different credentials for nightly and release.

Notes:

• in some places the configuration variants denoted as nightly are used in other places too (e.g. setup-branch).

Follow-up:

• after this gets merged, incubator-kie-kogito-pipelines PR needs to be backported also into branches:
  • seed-drools-10.0.x
  • seed-kogito-10.0.x
  • seed-optaplanner-10.0.x
