fix: App Store compatible icons (#926)

## 📜 Description

Remove transparency around borders to meet App Store requirements.

## 💡 Motivation and Context

I'd like to have an ability to submit app to App Store to see if
codebase has any violations.

## 📢 Changelog

<!-- High level overview of important changes -->
<!-- For example: fixed status bar manipulation; added new types
declarations; -->
<!-- If your changes don't affect one of platform/language below - then
remove this platform/language -->

### Example
- remove icon transparency

## 🤔 How Has This Been Tested?

Tested via App Store submit.

changed
