Docs outdated about internationalization in Numerictextbox

[Gorzas]

I've just to work with Numerictextbox component to use different locale formats for numbers and I've found there are discrepancies of usage in the documentation page of Numerictextbox. According to the page Common -> Internationalization, it suggests to install the library @syncfusion/ej2-cldr-data instead of cldr-data. There's an small difference between both libraries as cldr-data requires to run a post-installscript. Could we synchronize Numberictextbox doc page to say the same than TypeScript configuration?

Also, the Angular Numerictextbox doc page says to load the JSON files in the app.ts file when there's no such file in the last versions of Angular. It isn't a big deal but it could confusing for developers when reading the docs.
