[I18n] New locale codes not supported by angular.json

[floreks]

According to I18n documentation, language code such as zh-Hant-HK should be supported. Documentation also points you to the list of all supported locales on the angular repo.

It seems however that those codes are blocked by the regular expression defined in the schema.

angular-cli/packages/angular/cli/lib/config/schema.json

Lines 416 to 420 in c9a5f3c

	"locales": {
	"type": "object",
	"additionalProperties": false,
	"patternProperties": {
	"^[a-z]{2}(-[a-zA-Z]{2,})?$": {

Thank you for pointing this out. It was actually updated above that line but this instance appears to have been missed. A fix will be available in the next patch release.
