"Expand" instead of "Show more"

[paulo-graca]

Describe the bug

Currently, when we have large description or abstract, a "show more" button or link is shown:

but, that action is just to expand the text, not to show the detail of that item. And if we click on it, the text will expand and a "Collapse" action is shown at the bottom:

the opposite action for "Collapse" is "Expand". So I think, for best usability, the label should be renamed.

To Reproduce Steps to reproduce the behavior:

1. Just navigate in demo.dspace.org and find an item with a large description/abstract

Expected behavior Perhaps an appropriate action could be "Expand" instead of "Show more" since its the opposite action for "Collapse".

"Expand" matches "Collapse", and "Show more" matches "Show less". One pair is not so meaningful to people who don't spend their days thinking about UI design, and the other is ambiguous: show more or less of what? (Also, the control doesn't collapse; it still shows content.) What is a widely understandable complement of "Show full description"/"Show full abstract"? The intent is to make room for more controls to be visible concurrently by truncating their visible content. "Show abbreviated description"? "Show less abstract"?

@mwoodiupui I don't oppose to have it more descriptive. The only reason I raised this is because of the need to translate those labels into our native language and if those terms are accurate in the origin, then we don't need to use alternative expressions, in our native language, to better lead our users. Also: "Show more", in term of usability, is broadly understood as the action to access the detail for that record.
