Tails signing key can't be imported from Seahorse with the default key files filter

Tails signing key as we propose to download it (https://tails.boum.org/tails-signing.key) can’t be imported in Seahorse without changing its extension to “.asc”

It seems to be a Seahorse issue (same behavior in Debian Sid), since .key is supposed to be a valid mime type.
