use Standard_A1_v2 instances instead of Standard_A0

Standard_A0 instances seem no longer available and thus our tests
fail (see https://github.com/pulumi/examples/actions/runs/19534123403/job/55923956447?pr=2205)
for example.  Looking through the list of available sizes,
Standard_A1_v2 seems to be the closest available one.  Use it.
