Wrap pipeline artifact dropdown item names

What does this MR do?

For #334069 (closed)

This MR adds a text wrapping class to the items in the artifacts dropdown on the pipelines list page. We are doing because long artifact names without spaces or -'s get cut off when they extend past the width of the dropdown.

Screenshots

before 🙁	with this MR (.gl-word-break-word) 🤔	an alternative solution (.gl-word-break-all) 🤷🏻
secret_detection:secret_detection doesn't break and gets cut off	break long words like secret_detection:secret_detection if we have to, but prefer to break on spaces and -	break anywhere - takes up fewer lines overall, but makes the names harder to read

How to setup and validate locally (strongly suggested)

1. run a pipeline that generates artifacts
2. navigate to the pipelines list page
3. click the ⋮ (vertical ellipsis) button next to the pipeline to open the "Download artifacts" dropdown
