Allow customization of titles/headers of homepage widgets

Is your feature request related to a problem? Please describe.
One of our journals wanted a "Blog" widget on the homepage. The "News" widget functions more-or-less like a blog, and we could easily repurpose it for them if we were able to edit the header that displays above the widget on the homepage to say "Blog" rather than "News".

Describe the solution you'd like
Enable journal editors (or at least admins) to customize each widget's "display name" that displays as a section heading on the homepage.

Oh--we would also need the customized title to display on the actual news page (i.e., https://journals.publishing.umich.edu/[journal]/news/) as well as in the header of the widget on the homepage.
