[INFRA] Improve GitHub workflow and remove duplications

Introduce a local action to manage the npm cache and dependencies installation. All workflows now
use it to ensure that the setup is done in same way everywhere.
The surge preview won't generate teardown errors when the domain doesn't exist. This occurred when
closing PR created by Dependabot.
