At Kim's request, onboard the two bulk import packages into Konflux.

• include them in the supported list; remove them from the techpreview list: https://github.com/redhat-developer/rhdh-plugin-export-overlays/pull/1640
• sync change to downstream https://gitlab.cee.redhat.com/rhidp/rhdh-plugin-catalog/-/jobs/44038535
• onboard to pyxis: ./build/scripts/generatePyxisConfigForPlugins.sh -v 1.9.0
• onboard new KRD components: ./build/scripts/generateKonfluxReleaseDataForPlugins.sh -v 1.next
• regen PLRs for the two packages: ./.tekton/generatePipelineRunsForPlugins.sh -v 1.next --regex bulk-import --trigger
• build in Konflux: https://konflux-ui.apps.stone-prod-p02.hjvn.p1.openshiftapps.com/ns/rhdh-tenant/applications/rhdh-plugin-catalog-1/activity/pipelineruns?name=bulk
• check output in quay: ./build/scripts/checkPluginsExist.sh to verify new content
• re-run sync-midstream.sh to see if new metadata, plugin_builds/, or catalog-index content is created
