RFR 7061590 : Javadoc issues in Charset and StandardCharsets

[Ivan Gerasimov]

Hello!

A few small javadoc issues.

The most visible one is that the last dot in abbreviation a.k.a. is 
treated as a period, so the generated description appears broken (see 
[1] 
<https://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/nio/charset/StandardCharsets.html>):

static Charset    ISO_8859_1    ISO Latin Alphabet No. 1, a.k.a.
static Charset    US_ASCII      Seven-bit ASCII, a.k.a.
...

Would you please help review the fix?
