feat(actions): aggiunti LaTex Checks SubCheks

Migliorata l'action che controlla i file LaTex:

- Migliorati nomi e titoli degli step con l'aggiunta di emoji 🦍🚀🎸
- Aggiunti SubCheks: ora viene fatto eseguire il linter Chktex, un
  software che controlla lo stile di come è scritto LaTex (tipo 'questa
  frase non inizia con la maiuscola' oppure 'non si mette la
  punteggiatura prima di una parentesi chiusa', ecc.) ed un software per
  l'analisi grammaticale (questo ha bisogno di un file di
  configurazione).

Questi miglioramenti sono stati effettuati per rendere più semplice
capire com'è stata scritta una certa parte in LaTex (e capire subito
quando bisognerà bestemmiare 🙃)
