Pin tensorflow_version on TPU Node Full Test so that the test passes

Pin tensorflow_version on TPU Node Full Test so that the test passes. Fixes hashicorp/terraform-provider-google#16703

Because mmv1/products/tpu/Node.yaml already uses tpu_node_full.tf.erb for documentation and tpu_node_full_test.tf.erb for tests, this change shouldn't affect public documentation since we are just updating tpu_node_full_test.tf.erb.

Hello, @zeleena , did you run the test TestAccTPUNode_tpuNodeFullTestExample locally and did it pass or not?

[zeleena]

Hi @zli82016. I ran the test locally. On its own it fails with

bootstrap_test_utils.go:428: Error bootstrapping shared test global address "tf-bootstrap-addr-vpc-network-1": googleapi: Error 400: Invalid value for field 'resource.network': 'projects//global/networks/tf-bootstrap-net-vpc-network-1'. The project '' was not found., invalid

which seems unrelated to the fix here. Instead, it seems related to the test_vars_overrides on network_name and the function acctest.BootstrapSharedServiceNetworkingConnection(t, "vpc-network-1").

I had to modify the networking aspects to mirror the basic example. It may still hit capacity errors, but that is retry-able, and when it can get the capacity, the test passes

$ make testacc TEST=./google/services/tpu TESTARGS='-run=TestAccTPUNode_tpuNodeFullTestExample'
TF_ACC=1 TF_SCHEMA_PANIC_ON_ERROR=1 go test ./google/services/tpu -v -run=TestAccTPUNode_tpuNodeFullTestExample -timeout 240m -ldflags="-X=github.com/hashicorp/terraform-provider-google/version.ProviderVersion=acc"
=== RUN   TestAccTPUNode_tpuNodeFullTestExample
=== PAUSE TestAccTPUNode_tpuNodeFullTestExample
=== CONT  TestAccTPUNode_tpuNodeFullTestExample
--- PASS: TestAccTPUNode_tpuNodeFullTestExample (269.03s)
PASS
ok  	github.com/hashicorp/terraform-provider-google/google/services/tpu	269.162s

This fix won't address the capacity errors, but it will address the random set of Tensorflow versions bug.

BootstrapSharedServiceNetworkingConnection

Thanks for testing it locally.

The reason for bootstrapped network error could be that the environment variable GOOGLE_PROJECT is not set locally and is not related to this PR.
