Notifying the readers about the change in default value in context example

The example given for context (Passing Data Deeply with Context) starts with a default value of 1. Later on, for explaining 'Using and providing context from the same component', it is changed to 0 and remains the same for a later subtopic too.
While I was going through the example, I was left confused about how the code (shown in the below screenshot) is working given that the default value is set to 1 until I checked the 'LevelContext.js'.

While one can look at the 'LevelContext.js' and check, I think it would be better to make readers aware of the change! We can add a small sentence like 'Note that the default value is changed to 0'

Inizia dall’esempio “Passing Data Deeply with Context” e confronta il valore predefinito visualizzato con LevelContext.js, quindi leggi la sottosezione “Using and providing context from the same component”. Aggiungi una breve nota nel punto in cui l’esempio cambia a 0 e conferma che la sottosezione successiva rimane coerente con questa spiegazione.
