[CI][stable-only] Fix horizon-cross-ironic-ui-npm job

Zuul says there is a configuration error as there does not exist a job
named 'horizon-nodejs10-run-test'. In yoga the supported runtime [1]
was already NodeJS 14, and the defined job is horizon-nodejs14-run-test
as well, and there is no NodeJS 10 based job anymore. This patch
replaces the parent job from horizon-nodejs10-run-test to
horizon-nodejs14-run-test of horizon-cross-ironic-ui-npm.
