This Pull-Request is a backport of #2774 to the dspace-9_x version

@marsaoua : Thanks for this backport. Just a few notes below though that it appears that the translations in this PR are different from those on the main branch (and in #2774). Is this purposeful or accidental?

Obviously it may be best to ensure we have identical translations in both branches.

@marsaoua : I'm a bit confused because this change didn't occur in #2774. So, this means 9.x has a different translation that the main branch.

@tdonohue something is defenetly wrong, 9.x has a different translation that the main branch. I did not think to much and just cherry-picked the 3 commits from #2774. But it seems that only this commit 027a5ec was merged.

These last two translations are also different in #2774. In that PR and on main, these are translated as Dienstleistungen and Dienstleistung. So, this is another example of a place where the translations look to be different.

I do not find these lines on the main nor on 9.x branch. Those 2 lines are from #2774 commit 4ca1edf
