feat: Added images to PWA shortcuts

[Choromanski]

What type of PR is this?

• bug
• feature

What this PR does / why we need it:

It adds icons to the PWA shortcuts, currently on android the shortcuts have a white square next to them. This adds icons that match the menu bar.

Which issue(s) this PR fixes:

None

Special notes for your reviewer:

I kinda guessed where to put the SVGs and what to name them as they need to be publicly addressable. I'm open to changing there location/names.

Testing

Built the docker container and was able to get the images to work, no other functionality has changed.

LGTM, though I'm a little confused why this works; @boc-the-git any idea why this seems to work and it didn't work on your initial PR? Maybe because they're svgs?

Initial PWA shortcuts PR: #3255

[Choromanski]

It looks like they only defined the app icons and didn't define any shortcut icons.

In boc's initial commit he did, he just removed them since they didn't work: 00f32ae

It's super finicky when I tried putting the "type" field in it didn't work.

No idea. Maybe I tried png only and it didn't work. Maybe something else.

This PR makes me extremely happy! Well done @Choromanski
