InstallSTKResourcesTask still uses deprecated InstallResource(s)Task, which always strips extension of resource file name when installing.

Since MGNLRES-181; we want to avoid duplicates with other resource origins (classpath/filesystem), so extensions will be re-added to pre-existing resources.
Consequently, we must stop stripping extensions for fresh installs too.

• Replace usages of deprecated InstallResource(s)Task in InstallSTKResourcesTask
  • Use InstallBinaryResource(s)Task and InstallTextResource(s)Task instead
  • Set stripExtension to false

Update: MGNLRES-181 only provides the resource upgrade task, re-adding extensions to node names. This task should be used here in a delta in STK VH.
