ART-18521: switch networking-console-plugin pkg_managers from yarn to npm (4.18)

[joepvd]

Summary

Switch pkg_managers from yarn to npm for networking-console-plugin on openshift-4.18.

The upstream source uses package-lock.json (npm), not yarn.lock. The hermeto/yarn
prefetch handler fails because it cannot determine the yarn version — there is no
packageManager in package.json and no .yarnrc.yml in the repo.

This aligns with openshift-4.20 which already uses pkg_managers: [npm] and builds
successfully.

Failing build: https://art-build-history-art-build-history.apps.artc2023.pc3z.p1.openshiftapps.com/?name=^networking-console-plugin$&group=openshift-4.18&assembly=stream&engine=konflux&outcome=failure

Analysis

The hermeto prefetch step fails with:

ERROR PackageRejected: Unable to determine the yarn version to use to process the request
Ensure that either yarnPath is defined in .yarnrc.yml or that packageManager is defined in package.json

The upstream repo has package-lock.json (npm) across all branches (4.18, 4.19, 4.20).
The 4.20 ocp-build-data config already uses pkg_managers: [npm] and builds fine.

Changes

• Changed content.source.pkg_managers from [yarn] to [npm]
