<i18n dev> RFR: 8367704: Fix minor documentation issues in java.time.** [v4]

[Pavel Rappo]

> Please review this documentation-only change, which I believe does **NOT** require CSR.
> 
> The change touches java.time.** classes that I happen to have been using a lot recently. While the diff is pretty self-describing, here's the summary of what I did:
> 
> * used a comma separator for some big integer values, to improve readability;
> * fixed a few typos and grammar.
> 
> While I'm open to discuss the change, I also have some questions. Note: I'm not attempting to address those questions in this PR.
> 
> * What's the significance of the second argument in Duration.between(Temporal, Temporal) being exclusive? For example, would the result of the following call be different if the second argument was inclusive?
> 
>         Duration.between(Instant.ofEpochSecond(1), Instant.ofEpochSecond(2))
> 
>   Are there any cases here where that distinction matters?
> 
> * In many cases, the following phrase is used throughout documentation:
> 
>     > positive or negative
> 
>     While the intent is clearly to stress the directed nature of values, shouldn't we -- for completeness -- also mention zero where applicable?
> 
> * What's the significance of title-case for Java Time-Scale? FWIW, the documentation also uses "Java time-scale".
