[EmbeddedAnsible] Fix stdout sanitization

[NickLaMuro]

Second half of this PR ManageIQ/manageiq#19320

Since the API is now passing the full html source (for the moment), don't sanitize the HTML passed back from the API to retain it's formatting.

LGTM @NickLaMuro , thanks!

Matches what ui-classic does in ansible-raw-stdout.

(Except SUI is now asking the orchestration stack for stdout, instead of the task that retrieves it, which makes me think this is probably another place where we're blocking API calls to wait for an external service response nope, just assuming such task has already run and is associated with the stack, but that's unrelated to your BZ.)

@himdel Awesome, glad I didn't bang my head against the wall for this one on Friday for nothing. Thanks for the review!
