[aristosvo]

Required for at least #13514 and #9740

• Builds on Upgrade to v58.0.0 of Azure/azure-sdk-for-go #13613

Acceptance tests

I just ran a random test to verify the basics are working, which seems to be the case:

❯ go install && make acctests SERVICE='servicebus' TESTARGS='-run=TestAccServiceBusTopic_update'
==> Checking that code complies with gofmt requirements...
==> Checking that Custom Timeouts are used...
==> Checking that acceptance test packages are used...
TF_ACC=1 go test -v ./internal/services/servicebus -run=TestAccServiceBusTopic_update -timeout 180m -ldflags="-X=github.com/hashicorp/terraform-provider-azurerm/version.ProviderVersion=acc"
=== RUN   TestAccServiceBusTopic_update
=== PAUSE TestAccServiceBusTopic_update
=== CONT  TestAccServiceBusTopic_update
--- PASS: TestAccServiceBusTopic_update (382.31s)
PASS
ok      github.com/hashicorp/terraform-provider-azurerm/internal/services/servicebus    383.856s
