[chore] Unskip examples gen for `alicloud:fc/service:Service`

[guineveresaenger]

https://github.com/pulumi/pulumi-alicloud/blob/master/provider/resources.go#L2593 ensures we do not generate examples for a problematic doc comment formatting issue, pulumi/pulumi#13886.

When that issue is fixed, we can unskip examples gen for that resource's docs.
