Display error messages for each failure

[mgoerens]

Currently, only the error message related to the first failing step is communicated to the user.

development/scripts/src/pullrequest/prepare_pr_comment.py

Lines 233 to 256 in dcce7a5

	if pr_content_result == "failure":
	detail_message = append_to(
	detail_message, prepare_pr_content_failure_comment()
	)
	gitutils.add_output("pr_passed", "false")
	elif run_verifier_result == "failure":
	detail_message = append_to(
	detail_message, prepare_run_verifier_failure_comment()
	)
	gitutils.add_output("pr_passed", "false")

	if community_manual_review:
	outcome = "Pending Manual Review"
	detail_message = append_to(detail_message, prepare_community_comment())
	gitutils.add_output("pr_passed", "true")

	detail_message = append_to(detail_message, prepare_failure_comment())

	else:

We should consider displaying error messages for each failure that was received rather than only for the first one.

This appears doable. From reviewing the snippet shared, it seems that would mean breaking the conditions to be separate. So that each of the failures could be evaluated independently.
