* configs/configupgrade: detect invalid resource names and print a TODO
message
In terraform 0.11 and prior it was possible to start a resource name
with a number. This is no longer valid, as the resource name would would
be ambiguous with number values in HCL expressions.
Fixes#19919
* Update configs/configupgrade/test-fixtures/valid/invalid-resource-name/want/resource.tf
