fix(example/vmseries_standalone): Resolve problem with unstable VM-Series standalone example tests

[sebastianczech]

Description

From time to time VM-Series standalone example tests are failing during release e.g. https://github.com/PaloAltoNetworks/terraform-aws-swfw-modules/actions/runs/10294382059/job/28492474494

In order to solve the problem with S3, additional retry was configured.

Motivation and Context

From time to time release workflows fails.

How Has This Been Tested?

Code was tested via ChatOps.

In execution https://github.com/PaloAltoNetworks/terraform-aws-swfw-modules/actions/runs/10364614423/job/28690221035 there was a problem with S3 objects, but workflow didn't fail - it just retried once again after 5 seconds (by default there are max 3 retries):
