Rename foie gras to faux gras

[RabblerouserGT]

Summary

None

Purpose of change

By the old description's own admission, it's technically not foie gras, which I feel opens this up for a possible rename. The old description also seemed somewhat bland.

Describe the solution

I'll be frank, I saw an opening for a pun a la the cannibal recipes and figured it'd be an easy first ever project to change the name from foie gras to faux gras. Description seemed bland, so I figured I'd change it as well.

Describe alternatives you've considered

Leaving as is. Or changing the systems of the game to differentiate meat by the animal they come from. Even more unlikely, adding force-feeding ducks while they're still alive to enlarge their liver. These options are beyond my capability.

Testing

Ran the game with the changes, even with Aftershock installed, which has a recipe override for foie gras, though I'm not sure how thorough my test was. This is my first attempt at a PR for this game, so I have no context of what's thorough or not.

Additional context

The id was left as is since I doubt the very specific methods of creating actual foie gras (force feeding a duck through a tube) will ever be implemented. This was a learning exercise for me in both the game systems and git, thus I won't be too upset if it's denied.

It might prove hard for translators to properly translate the pun.

[RabblerouserGT]

I never really thought about translators. I imagine they have a fit trying to translate the cannibal dishes. I won't be too bummed if it's a non-starter, though. I learned a lot from something so simple.

It's okay to have word play or pun only in English, so your PR is okay too.
