[SD-613] add unused apple icons to prevent requests loading up site

[lambry]

Issue: https://digital-vic.atlassian.net/browse/SD-613

Note: This as a draft for now as the backend needs the app icon field re-added: https://digital-vic.atlassian.net/browse/SD-666

What I did

• Add unused apple icons to prevent requests loading up site

In sumo you can see requests to a few different apple-touch-icons, these requests occur when safari users use the native share functionality. Despite the fact that we 'register' the correct icon using the link rel tag and webmanifest safari will still make background requests to apple-touch-icon-precomposed.png even though it never uses that file. It seems like the precomposed files haven't even been needed since ios 7. Adding these requested files here prevents these background requests from firing up the site and subsequently making several API requests to Drupal, it also avoids sumo be flooded with irelevant logs about 404'ing files that aren't used.

Testing

I've tested the following devices to make sure the correct icons are still used when clicking share and adding the site to home screen.

• iOS 18

• iOS 17

• iOS 16

• iOS 15

• iOS 14

• Android

• Android 14

• Android 13

• Android 12
