Warning icon is poorly visible in the "Facebook Instant Games" build profile window

Steps to reproduce:

1. Create a project
2. Go to "Unity" -> "Settings" -> "General"
3. Find "Editor Theme" and set it to "Light"
4. Go "File" -> "Build Profiles"
5. Click the "Add Build Profile" button in the details window
6. Select "Facebook Instant Games"
7. Observe displayed icons

Actual results: The first smaller icon displayed below the "Facebook Instant Games" is poorly visible

Expected results: The icon should be brighter. It should be adapted to the "Light" theme.

Can’t test with versions: 6000.3.0b9, 6000.4.0a5, 6000.5.0a2, as these streams do not have a message with the mentioned icon
