Split revision descriptions at a new line — radicle-desktop

In the revisions listing we are trying to display the whole revision text, which should be trimmed at a new line, or after an amount of chars.

             <RevisionBadges {revision} {revisions} />
             <span class="txt-overflow">
               {#if revision.description[0].body.trim()}
                 {revision.description[0].body}
                 {revision.description[0].body.split("\n")[0]}
               {:else}
                 <span
                   class="txt-missing"
