Currently, a code suggestion is bound to a version of a merge request, meaning, when the surrounding code changes, the code suggestion is marked as outdated, no matter if it _could_ potentially still be applied, because it might not. There's no way to try to apply the suggestion.
It would therefore be nice to have an option to either
* Resubmit the suggestion for the new version
* Try to apply the suggestion anyway and then resolve merge conflicts (if there are any)
Furthermore, it would be awesome, if the reviewer could get a similar notification when their suggestion is outdated to the one, the assignee gets when the branch as merge conflicts with the target branch
