[locale] lv: Avoid trailing dot after short date, fixes #4136

[ashsearle]

As reported, and confirmed with:

Intl.DateTimeFormat("lv", {
  day: "2-digit",
  month: "2-digit",
  year: "numeric",
}).format(new Date());
// "21.08.2017"

@JanisE any thoughts on this?

This is not correct. Wikipedia does not have the right format, besides its reference is broken.

• In the European Union website, there is an interinstitutional style guide (http://publications.europa.eu/code/lv/lv-4100500.htm#1052) that states that the trailing dot is supposed to be there (see the example "21.9.2002." in section 10.5.2.).
• In Likumi.lv ("Likumi.lv is a legislation website ensuring free access to systematized (consolidated) legislation of the Republic of Latvia.") you can see the regulations about format of documents (https://likumi.lv/doc.php?id=219491), which includes section 3.2 about writing the date (see the example "03.05.2010."). The use of dots is specified in sentence "Aiz katras ciparu grupas kārtas skaitļiem liek punktu."
• Also, a year ago there has been a radio broadcast about how to write various type of numbers in Latvian correctly – in Latvian national radio channel "Latvijas Radio 1", and the short description of the broadcast (http://lr1.lsm.lv/lv/raksts/ka-labak-dziivot/skaitla-vardu-pareizrakstiba-latviesu-valoda.a67352/) informs that during the talk an expert from The Latvian Language Agency (http://www.valoda.lv/en/about-us/) had talked just about how the dot after the year must be written.

I find @JanisE's bullets convincing, so closing this out.
