feat: Enable X-Ray tracing on Step Function if set to true in service_integrations

[nolivermke]

Description

Check if the service_integrations variable contains a key for xray and check if its sub object is set to true. If so enable xray tracing on the step function by setting the tracing_configuration block with enabled equal to true.

Motivation and Context

Currently there is no way to enable XRay tracing with this module. Setting the service_configuration object sets up the IAM permissions but does not actually enable XRay tracing on the step function.

Breaking Changes

Possibly would cause unexpected behavior for users who expect XRay tracing to not be enabled because that is how the module currently functions.

How Has This Been Tested?

• I have tested this using an express workflow step function that already had the XRay service_configuration value set to true. The only change to my existing TF file was the tracing_configuration value went from false to true.

      ~ tracing_configuration {
          ~ enabled = false -> true
        }

• I also tested by removing the XRay service_configuration block and there were no changes to my current Terraform state.

Hate to be that person but is there anything I can do to help get this reviewed and merged or rejected?

Our team is super grateful for this module and use it in a number of places but it would be nice to not have to manually enable x-ray tracing on our step functions.

Thank you for the PR and for the nudge! Merging this now...

My and other maintainer's focus has shifted a bit to other modules like the EKS module during the last few weeks.

v2.4.0 has been just released.
