Change Newtonsoft deserializing bug comment to link to the new issue

[adamgauthier]

PR Summary

This is a follow up to reverted PR #8346. I removed a workaround that was used to avoid a Newtonsoft.Json bug that caused some incomplete json array input to successfully be deserialized.

This bug being fixed, I thought the workaround was unnecessary, but after the merge some feature tests started to fail (which I did not run prior to merging).

It was discovered that the workaround is still needed because while the first Newtonsoft.Json bug was fixed, some cases of incomplete json array input still behave unexpectedly, namely json input [.

This PR is just to update the comment explaining the workaround so it links to the newly created issue here.
