[SKU] add localizations for SKU name and benefits

[kingmigdor]

Why this is needed:

• adding localizations makes it more trustful for a different language/country to determine whether to subscribe or not. If a bot is localized but a screen of the bot pops up which isn't localized and is indeed about buying something, it may at least get confusing or untrustworthy.
• people who aren't as good at english as in their language may not really understand what the benefits are

Maybe it's a great idea to add localizations for the SKUs which we can setup in the developer portal such as how the app directory works.

We have plans to enable localizations for SKU names & benefits in the future. Appreciate the feedback 😎
