Update terms for objects on game mode pages

[Joehuu]

~Need the right object terms for every game mode for ppy/osu#2337. And nice if someone(me) could update it.~

I guess you don't need them anymore since the other PR is closed? In that case you should close this issue

[Joehuu]

No, it hasn't been done yet in the wiki pages. The correct terms are in ppy/osu#2492, and it needs to be applied in the articles. Will do that.

to save time, the updated terms and their osu! analogs are below (taken from https://github.com/ppy/osu/blob/master/osu.Game.Rulesets.Catch/Beatmaps/CatchBeatmap.cs for example)

osu!catch

• circle: fruit
• slider: juice stream ("drop" and "droplet" need to link to specific sections of https://osu.ppy.sh/wiki/en/Gameplay/Hit_object/Juice_stream on first occurrence)
• spinner: banana shower

osu!mania

nothing new really

• circle: note (I saw this sometimes being referred to as a "key")
• slider: hold note

osu!taiko

• slider: drumroll
• spinner: swell (instead of denden, which is apparently a taiko no tatsujin term)
