Remove QtPositioning module from qtlocation.git6.2.46.2.36.2.26.2
Turns out that our CI does not support repos without any tests. This is treated like an error and leads to integration failure. This patch fixes it by disabling tests in coin/module_config.yaml. This config should be fixed when QtLocation tests are enabled Task-number: QTBUG-97084 Change-Id: Ib06e865fe2836806bbbee34345f06b471dd48660 Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Alex Blasche <alexander.blasche@qt.io> (cherry picked from commit 23f32792ad53e23bbafbff6d7667f0bb0f69fc53)
