[Icon request] Support format-text-underline-squiggle icon

[ferroson]

• App Name:Okular
• Icon Name:format-text-underline-squiggle
• Description:I want to request an icon, but what I mean is not an icon for the application, but a button icon. I'm using Okular and I found that Papirus shows the same icon for format-text-underline and format-text-underline-squiggle.
• Webpage (optional):
• Original Icon:

You can see that the underline and underline-squiggle icons look the same

This is how the icon looks in Breeze icons (KDE default)
