AzOps Accelerator - can we add AZOPS_CUSTOM_SORT_ORDER on workflows other than 'Redeploy'?

Issue

I'm currently using repo bootstrapped from https://github.com/Azure/AzOps-Accelerator

I had to redeploy some assets, so I added them all back in in bulk to deploy to one resource group. This was achieved by taking 3 templates I had and adding it to a folder. After merging this to main, the 3 templates deploy. Unfortunately, the 3 do not deploy necessarily in the sequence I want.

I think it would be a good idea to allow custom sorting of templates to deploy within Push. I have tested this by modifying az-platform-ops/.github/workflows/push.yml manually, but this is flakey esp with the AzOps - Update workflow trying to remove it. Plus if it isn't included, there may be a reason for it that I'm keen to learn.

PS: I thought this would be great for validate too - but WhatIf obviously doesn't work well for this scenario as we can't track deployment of each template and its effect if there is a dependency in the next template. This opens up an issue imo - something may appear to fail validation even though the push would succeed because it requires actual deployment of templates in sequence to resolve dependencies properly. I don't know the answer to this (it feels like a damned-if-I-do-damned-if-I-don't situation). Again, open to hear thoughts on that

A second thought is - there's no harm in adding it for "Validate" workflow too, as it at least allows us to verify the deploy order in PR before we merge. So I advocate we add it into "Validate" too
