Add Trello brand icons and logos

[ScottG489]

Proposed change

This supports the addition of the Trello integration into core.

These icons and logo files were created by modifying the official Brand Assets to meet the image specifications of this project (size, file type, etc.).

The only thing to note is that I intentionally didn't include different icons for dark/light mode because the standard Trello icons seemed to work well for both. Happy to discuss further.

Image file information for quick reference:
