[8.x](backport #5910) [Integration Testing Framework][ESS] Stop using deprecated ESS resource IDs

[mergify]

What does this PR do?

This PR updates the deployment template IDs and instance configuration IDs used to spin up deployments in ESS for integration testing.

Why is it important?

The deployments template IDs and instance configuration IDs being used have been deprecated. Continuing to use them causes errors like so when the integration testing framework attempts to create deployments in ESS:

failed to create ESS cloud for version 8.17.0-SNAPSHOT: failed to create: (deployments.elasticsearch_using_legacy_dt) The referenced deployment template in elasticsearch plan [gcp-storage-optimized-v5] is no longer available.

failed to create ESS cloud for version 9.0.0-SNAPSHOT: failed to create: (deployments.topology_element_using_legacy_ic) The referenced instance configuration [gcp.integrationsserver.n2.68x32x45.2] in topology element [<unknown>] is no longer available.
