[Discovery] - Update logos

[andycwilliams]

Describe the Current Behavior/Feature:

The current logos we have been using are placeholders and may or may not be the final designs we want.

Rationale:

The logo is a key part of an app's branding and more focus should be dedicated on it than we have allowed.

Proposed Changes:

Get the UX team's recommendations for logo updates, then replace the existing ones with those.

Ensure that the resolution is high enough for any given screen size. Currently, it is low resolution on some screens.

Possible Drawbacks:

As of this writing, an updated design has not yet been decided upon. So that must be resolved first.
