vertexai: reduce FeatureOnlineStore max_node_count, DeployedIndex max_replica_count, and ReasoningEngine resource limits in acceptance tests

Summary

Speed up and reduce compute cost of vertexai acceptance tests (non-overlapping with #19649):

• Reduce Bigtable auto_scaling.max_node_count from 2 to 1 (min_node_count = 1) on helper and non-scaling google_vertex_ai_feature_online_store resources across vertex_ai_featureonlinestore_featureview*.tf.tmpl, vertex_ai_featureonlinestore_with_beta_fields_bigtable.tf.tmpl, resource_vertex_ai_feature_online_store_featureview_test.go, and resource_vertex_ai_feature_online_store_test.go (preserving the scaling update test TestAccVertexAIFeatureOnlineStore_updated).
• Reduce max_replica_count from 2 to 1 (min_replica_count = 1) in vertex_ai_index_endpoint_deployed_index_automatic_resources.tf.tmpl and vertex_ai_index_endpoint_deployed_index_dedicated_resources.tf.tmpl.
• Reduce deployment_spec.max_instances from 3 to 2 and resource_limits from cpu = "4", memory = "4Gi" to cpu = "2", memory = "2Gi" in vertex_ai_reasoning_engine_full.tf.tmpl.

Caution

Issues requiring attention before PR completion

🔴 Initial Recording Failed: Some tests failed during the recording step. See the table above for details.

🟡 Known Nightly Failures: 2 of the tests that failed in recording also fail or are flaky in the last 30 days of nightly runs, so they may be unrelated to this PR. In nightly findings, ⚪ means the test already fails in nightly, 🟡 that it is flaky there, and 🔴 that it is healthy in nightly and so more likely broken by this PR.

Please address these issues to complete your PR. If you believe these detections are incorrect or unrelated to your change, please raise the concern with your reviewer.

View the recording VCR build log or the debug logs folder for detailed results.
