[Accessibility] Avoid repetition of identical link text on same page

[hostle83]

Describe the bug
This relates to items that have a number of different download options. For each option, the Download Link currently says "Download". According to Success Criterion 2.4.4 Link Purpose (In Context), the user should be able to determine the purpose of each link from the link text alone. In this example, users with screen readers would hear the word "Download" read numerous times but not know the context, purpose and destination of each download link.

To Reproduce
Steps to reproduce the behavior:

1. Visit https://sandbox.dspace.org/items/cd374806-70ac-4541-a711-559c9bb60a76/full
2. See list of Download Links at the right side of each file description

Expected behavior
A clear and concise description of what each link does, e.g. "Download the PDF...".
