Setup Plausible

[thePeras]

1. Use directly the api, no need to import external js.

2. Remove parameters from url, exame: ?pv_fest_id=1301550
   https://sigarra.up.pt/feup/pt/fest_geral.curso_percurso_academico_view?pv_fest_id=1301550
   and only send fest_geral.curso_percurso_academico_view

This issue is currently stopped as we have found some legality issues about user tracking on a website we do not control, also Sigarra might already have a way to do this.
