[REQUEST] Command localization

[i0bs]

What is the feature you're proposing?
With the name_localizations and description_localizations fields for an ApplictionCommand object currently being exposed from the Web API and Gateway event data, it would be nice in terms of user experience for bot developers to be able to specify the translated locale of their commands when a user has their locale set to a specific language and/or region.

This would be the suggested implementation:

@bot.command(
    name="hello",
    description="how are you?",
    name_localizations=interactions.Locale(
        interactions.Locale.GERMANY="hallo"
    )
    description_localizations=interactions.Locale(
        interactions.Locale.GERMANY="geht's dir?"
    )
)
async def command(ctx):
    ...

The new suggested data model, interactions.Locale would be a str, Enum metaclassed object with names representing the official Discord locale list.

Closed beta testing has now begun for command localization. Because of this, we'll be raising the priority status on this.
