Revert "Merge branch 'cngo-fix-issue-assignees-alignment' into 'master'"

Purpose of revert

This MR reverts !115973 (merged) as it is causing layout issues.

@cngo This MR subtly broke the layout at !115463 (merged), by raising the avatar icon above the text baseline: the issue is that inline-flex children will ignore css from classes like gl-vertical-align-top and make the behave different from a simple inline element.

I suspect other areas of the product also depend on this component, is there a chance more things broke?
