Allow opening ds-metadata-uri-values links in a new window

• Fixes #2834

Description

This feature request proposes adding a new optional input parameter to the <ds-metadata-uri-values> component in order to specify the link target, allowing metadata links to open in a new window/tab.

Instructions for Reviewers

List of changes in this PR:

• Added a new optional input parameter linkTarget to the <ds-metadata-uri-values> component. The default value of this parameter is _blank, this will make sure the link is opened in a new window/tab.
• Added a test case in the src/app/item-page/field-components/metadata-uri-values/metadata-uri-values.component.spec.ts to verify the correct application of the linkTarget attribute to metadata links.

How to test:

• Go to an item page, for example a publication
• Click on the link that's under the URI-title
• The link now opens in a new tab/window

Reason for changes: If the user clicks a link that leads away from DSpace, we want it to open in a new window.

Thanks @kunovercammen. This patch works well for me on DSpace 7.6.1. Our repository has many metadata fields containing URLs that should be opened in a new window (for example DOIs and other URLs on external sites).

This is a very minor change, but I wonder if @tdonohue will allow it in dspace-7_x since it changes the existing behavior? In any case, the base branch should probably be changed to main and then the port to dspace-7_x tag should be added if Tim agrees.

@kunovercammen : This seems reasonable to me for both 7.x and main. However, I cannot get this PR to apply cleanly to the main branch. Could you please create a second PR which can be applied to main? That way this can be more easily tested for 8.x as well.

From reading the code in d46248e99be7383fe3308d37d1d77be56b81f427 it seems this same functionality was introduced as part of the COAR Notify support recently merged in main for DSpace 8.0-SNAPSHOT.

Edit: I have just tested on sandbox.dspace.org (DSpace 8.0-RC1) and external links use target=_blank by default. Therefore this patch is not necessary on main.

Merging this for DSpace 7.6.1 as I have already tested it and this is 1 APPROVAL. Thanks @kunovercammen.
