fix(event-targets): ecsTask uses invalid task definition arn in policy (

#31615)

### Issue # (if applicable)

Closes #30390 . 

### Reason for this change

This is extending a closed PR #30484 by @jwoehrle . I couldn't update that PR so I am creating this new one.

Reason for this change is due to a AWS ECS campaign where they are asking customers to add task definition revision number (or wildcard as the revision number) to IAM policies.

### Description of changes

When adding permission to the Events Role to allow it to use the task definition, check if the task definition arn has a revision number, if yes, do nothing, if not, add the wildcard `*`. This is only done when the task definition arn is not using any token.

### Description of how you validated changes

Unit tests and Integ tests are added.
