[FR] - Feast of hemlock vale translation fixes

[Evelf]

Various fixes for the French translation, checked on the actual French cards.

• Kōhaku's ability reads ".. or remove 2 [bless] tokens and 2 [curse] tokens from the chaos bag ..", but current French translation is ".. ou retirez 2 pions ou 2 pions de la réserve du Chaos .." That ou (or) instead of et (and) makes a huge difference!
• Servant of Brass doesn't activate on a [bless] token but on a [curse] one.
• Fake Credentials (4XP) card is worded differently in French and English, "En cas de réussite avec un écart de 1 ou plus .." (In case of succeed with a difference of 1 or more ..) is actually "En cas de réussite avec un écart de 1 ou moins .." (In case of succeed with a difference of 1 or less ..) on the card.
