Wrong flag for Ingrian

[Guybrush88]

As reported by Thadh on the wall:

Hi!

I've noticed the flag used for Ingrian is incorrect.

Currently the flag of Ingria is used ( as https://commons.wikimedia.org/w...germanland.svg ), but this flag is only used by the Ingrian Finns, which speak a dialect of Finnish.

The orthodox Izhorians, which speak Ingrian, instead use this flag ( https://commons.wikimedia.org/w...Flag_igora.svg ). I think it's best to change this.

Thanks in advance,

Thadh
