Migrate to Pajamas compliant buttons in app/helpers/listbox_helper.rb

One or more buttons in app/helpers/listbox_helper.rb are not Pajamas compliant. See the parent epic &8153 for guidance on migration strategies.

As noted in !118983 (comment 1371960720), app/helpers/listbox_helper.rb is out of spec with the canonical button/dropdown implementations in GitLab UI (i.e., gitlab-ui!3233 (merged)).

Tasks

Render button using Pajamas::ButtonComponent
Update dropdown container classes to align with gitlab-ui!3233 (merged)
