Update Hardcoded Image File Paths for Homepage, MicroMasters Page and Professional Certificate Page

Background:
The institution image file paths on the Homepage MicroMasters page, and Professional Certificate page are all "hardcoded." These logo files are also used on the respective institution's Course About Pages and on the Schools and Partners page "shingle."

Simply matching the file names is not sufficient at this point as some places need a transparent PNG and others point to a JPG. Additionally, in one case we have two hardcoded pages using different logo URLs for the same institution.

Current Behavior:
The logo files are broken for the following institutions on the following pages:
HKPolyU - Homepage
USMx - Homepage
USMx - MicroMasters Page
IDBx - Professional Certificate Page
Catalyst - Professional Certificate Page

Pages
https://www.edx.org/
https://www.edx.org/micromasters
https://www.edx.org/professional-certificate
