Spanish version of Ultima VIII: Pagan not detected/supported

[AlWesker]

ScummVM displays the following message when trying to add the Spanish version of Ultima VIII: Pagan.

"The game in 'ULTIMA8\' seems to be an unknown game variant.

Please report the following data to the ScummVM team at https://bugs.scummvm.org/ along with the name of the game you tried to add and its version, language, etc.:

Since the standalone version of Pentagram is able to detect and run the Spanish version of Ultima VIII: Pentagram, I thought it would be much more straightforward for ScummVM to support it too.
