Remove the {{page}} macro

[wbamberg]

This came out of #3008. We should remove the {{page}} macro from MDN: it's a common source of content problems.

We will need to look through the 370-odd places where it's used, and decide what to do in each case. Probably either:

• duplicate the content
• have the content in one place and just use links to it in the other places

Thanks for creating this @wbamberg. It'll be nice to eventually resolve this and rid ourselves of this macro.

Happy to help hack away at this with you (once the broad discussion of "how" we do this is resolved).

FYI, Page macro search got me 420 hits in 351 files (of 11702 searched). Down to 385 hits in 316 files following easy fixes in #3392.

@hamishwillee , this is amazing work!

Do we really only have about 15 of these left?!

Yes. I'm seeing 20 hits in 16 files. BUT - still in translations ...

Fixed by #15906!

[hamishwillee]

Well done all. This was a slog.
