RFR: 8360575: java.util.Properties.list() methods trim each value to 37 characters in the listed output [v3]

[Jaikiran Pai]

> Can I please get a review of this doc-only change which proposes to clarify the current implementation of the `java.util.Properties.list(...)` methods?
> 
> As noted in https://bugs.openjdk.org/browse/JDK-8360575, the current implementation trims each value to a size of 37 when printing out the value. This behaviour isn't documented by these methods. The change in this PR adds an `@implNote` to make a mention of this current behaviour.
