Revise issues workflow so that pending::feedback label updates to pending::support after any response (not just author)

What is the idea?

Currently, the workflow only updates the labels (from pending::feedback to pending::support) if the author responds. The proposal is to update the labels if anyone responds. Also update comment on line 34 to indicate that the support label is being added and not the feedback label.

Why is this needed?

People other than the original author may respond to add sufficient clarity to an issue. The provision of additional information should trigger us taking another look.

What should happen?

If an issue has a pending::feedback label and anyone adds an additional comment, the label should switch to pending::support, regardless of whether the person commenting is the original comment author.

I'm planning to tackle the PR for this tomorrow.
