[FR] improved french translation

[sbnh1]

change in the following files :

• wiki/Gameplay/Combo_(score_multiplier)/fr.md
• wiki/Gameplay/Combo_fire/fr.md
• wiki/Gameplay/Combo_milestone/fr.md
• wiki/Gameplay/Combo_multiplier_effect/fr.md
• wiki/Gameplay/Comboburst/fr.md
• wiki/Gameplay/Full_combo/fr.md
• wiki/Gameplay/Health/fr.md
• wiki/Gameplay/Mind_block/fr.md
• wiki/Gameplay/Replay/fr.md
• wiki/Gameplay/Spectating/fr.md
• wiki/Gameplay/Spinner_trap/fr.md
• wiki/Gameplay/Tablet_cover/fr.md
• wiki/Gameplay/Unstable_rate/fr.md
• wiki/Gameplay/fr.md

I see that the categories "full combo", "health" and "hit object" were missing in the index (I’m not sure if this was intentional). I’ve added them to the last file mentioned.

I adjusted the phrasing and clarified the terminology in various sections to improve clarity.
