[UX] Priorities Page links to Tracking Issues/Discussions

[hawkerm]

The new Priorities page is great!

And it's great that there's anchor links to be able to link to specific priorities in within the page.

However, it'd be even better at helping direct folks to contribute/participate, if there were also links for each priority's underlying tracking issue or proposal/discussion. This way it can filter folks to the other repositories that contain the main discussion or latest information on that item.

This seems to happen within the specific details of some priorities currently inconsistently, like these two in assets:

But not for others:

For instance, the .NET Web export issue could link to this latest status comment here: godotengine/godot#70796 (comment)

It'd be great if a backing link was a required field for the priority to have in its metadata and bubbled up with a consistent icon for each priority, e.g.

Thought of this request based on a discussion of the latest status of a priority item that occurred in the Discord server starting here.
