[General] Update issue tracker's duplicate resolution message

[daverayment]

GitHub newcomers can be confused by the current duplicate resolution message, as it doesn't include a reference to the original issue - see #46347 (comment). They may not realise that the #12345 in the duplicate comment is the relevant link.

This small wording update to the duplicate resolution message tightens up wording slightly and includes reference to the prior /dup #nnn comment so newcomers don't miss it.

Note: I'm assuming we cannot reference the issue number itself. I can't access the GitHub bot's documentation pages to check.
