feat: Enable configuration of Docker labels (#303)

* feat: Add docker_labels

Allow the user to define a list of Docker labels without providing the
entire task definition.

* fix(ci): Update `cloudposse/dynamic-subnets/aws` to the most recent version

AWS provider v6 deprecated `vpc = true` for the EIP resource

* fix(ci): Ensure unique S3 bucket names

1. Bucket names now include a timestamp (10 digits) to ensure they're
always unique (previously it was a random number between 0 and 999,
which increased the risk of a name collision)
2. `rand.Seed` is deprecated, so it was removed. As of Go 1.20, there is
no reason to call Seed with a random value
