Add ability for flow to fix pipeline if no code change is necessary

Problem

As brought up in gitlab-org/modelops/applied-ml/code-suggestions/ai-assist!3256 (comment 2728055050) there are cases where a pipeline is just flaky or failing e.g. due to an external resource not being available. In these cases there is no code change necessary.

Desired Outcome

Flow can identify cases where no code change is necessary and either do the necessary action (e.g. re-run specific job) themselves or ask the user to do that.

Proposed Solution TBD
