Fix: Correct indentation on github-actions with aws inputs (#1602)

Why do we need this change?
=======================
The live documentation had inputs at the same level as the workflow-dispatch, this will result in an error if folks just copy/paste the results and attempt to run.

What effects does this change have?
=======================
* Fixes the indentation that the inputs are required in the workflow_dispatch:, and not at the same level.
