Both metadata values and separators appear on separate lines (see: item's keywords field)

[MMilosz]

Describe the bug

During the testathon, I observed that commit d8a3873 added d-flex flex-column to the metadata-field-wrapper.component.html, causing fields like 'Keywords' to appear incorrectly (both values and separators appear on separate lines)

This issue is only observed in DSpace 10

See: https://sandbox.dspace.org/entities/publication/01c5f86f-806a-41a8-840d-8373e697eb20

Current behavior

Pre-DSpace 10

To Reproduce

Create an item, add at least 2 subjects, and deposit it. Observe the separators appear on new lines

Expected behavior

Separators should appear inline between values

I’m not sure why the d-flex and flex-column classes were added. I think we can just remove them.
