RUN AS-IF-FOSS: Add canonical links for moved/duplicated/promoted issues
What does this MR do?
Duplicated/closed/promoted issues often appear first in Google search results, because they are older, but are out of date. This helps by making it so there's a canonical link to the current issue. This will ensure that the most relevant issue shows up in Google search results.
This adds a canonical link to any moved or duplicated issue's header that points to the issue that it was moved or duplicated to. To test, simply move an issue and see the new header value appear. No other issues should be changed.
Closes #222473 (closed)
