Landing Page Update: update links and text

[emquardokus]

On the landing page image for the reporter (can't find source to edit) there are two issues to address:

1. typo Hubmap should be HuBMAP
2. Hubmap Consortium website is linked to our old CCF portal---I assumed this meant the actual HuBMAP consortium website?
   Not sure which is intended but it needs to be updated.
   HRA portal: https://humanatlas.io/
   HuBMAP consortium website: https://hubmapconsortium.org/
   The CCF ASCT+B Reporter is a visualization tool for displaying anatomical structures, cell types, and biomarker (ASCT+B) authored by domain experts for different human organs. The tables are used to develop a common coordinate framework (CCF) of the healthy human body, see also Hubmap Consortium website.
