Update `Video` `play()`/`pause()` code, possibly clearing some Sentry errors

* `video.play()` and `video.pause()` return a promise and we should place our code in something like a `try` and `catch` block. Not doing so may be causing some errors that were caught by Sentry
* We could also use a `catch` block to take care of other Sentry `video` errors that we don't need to worry about

Individua le chiamate a `video.play()` e `video.pause()` nel sito web e consulta prima le indicazioni collegate di MDN e Google Developers. Usa gli errori Sentry collegati per capire quali rifiuti delle promise devono essere gestiti; il lavoro è completo quando gli errori rilevanti vengono gestiti senza introdurre regressioni.
