Enable InlinePanel commenting

[jacobtoppm]

Is your proposal related to a problem?

When #9649 is merged, commenting on InlinePanels will be disabled. This is a feature that was never intended to be enabled without further development, so had a number of issues: child models that aren't yet saved to the database do not have a stable way to identify them at present, causing issues tracking which child model a comment is attached to across revisions.

Describe the solution you'd like

We should enable commenting on InlinePanels. This could be by either:

• Allowing comment contentpaths to vary by revision, using the order of an InlinePanel as the identifying part of the contentpath for child models (so the contentpath would be relation_name.0 for the 0th instance), and updating it using the InlinePanel js when positions are changed. Downside: this is more fragile, especially when content is updated/reordered programatically.
• Coming up with some unique identifier (such a a uuid) for child models that have not yet been saved to the database, and using that as the identifying part of the comment's contentpath

A few thoughts

• We could do a partial solution by only allowing comments on items already in the database (however, this would be super confusing for users)
• We should, when re-enabling, either ensure we consider what will happen to comments already in the DB from when this feature used to work-(ish)

@SyedImtiyaz-1 feel free to read through this issue, the comments and related work.

However, I think this is not good first issue as it will take a lot of understanding of both the commenting system and the InlinePanel system. Both of which are quite complex.

Nonetheless, if you feel confident giving it a go - I suggest you get started on some ideas and write a comment when you are ready to present a proposed solution. Or a draft PR.

As noted on other issues, we do not really assign specific tasks outside of the core team.

If you haven't already, maybe introduce yourself in the Slack channel #new-contributors ping me and we can say hi and see how to get you started with a good first issue.
