Add link about grfp to news entry

[zsunberg]

@bkraske this is a simple exercise to get you used to working with the website:

There is a news entry about your grfp. Please add a link from that news entry to this announcement page:
https://www.colorado.edu/aerospace/2022/04/12/five-cu-boulder-aerospace-students-earn-major-nsf-graduate-research-fellowships

Once you are done, close the issue. Thanks!
