Update to latest Polygon logo

[evanaronson]

They've updated their logo since we launched with them last year

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist:

• I have tested the updated logo locally and it looks just fine - transparency in the png all good.
