refactor: mover lógica de âncora e título para abstracts sem título (#1209)

- Remover chamada a 'create-anchor-and-title-for-abstracts-without-title'
  do template 'text-abstracts', pois a lógica agora é aplicada
  individualmente por cada abstract/trans-abstract
- Esvaziar template 'create-anchor-and-title-for-abstracts-without-title'
  que era aplicado ao nível do elemento pai
- Mover lógica de geração de âncora e título para o template
  'anchor-and-title' de abstract[not(title)] e trans-abstract[not(title)]
- Substituir chamada a 'text-labels' por 'translate' com parâmetro 'term'
  para tradução do termo 'Abstract'
- Determinar idioma dinamicamente via @xml:lang do próprio elemento,
  do avô ou do bisavô, com fallback para 'en'
- Remover lógica condicional de singular/plural (Abstract vs Abstracts)
  em favor de tradução fixa do termo 'Abstract'
