Update sv-SE.json

[haf]

We write 4 566,00 kr (sv punct, sv spacing, sv locale) for SEK 4,566.00 (en). Not SEK4566,00 and not kr4566 and not 4566kr. We accept 4566.00 kr (en punct, en spacing, en locale) when writing things internationally and the context is clear; otherwise 4566.00 SEK is common if the (currency) context is unclear. In accounting, negative balances are red and with a negative sign and without currency specifier (contextual), like so: 4566 or -4566 (imagine that text being red).

Thanks for the fix!
