fix(content): thessalia dialogue, bunny_ears, scythe

[dhemms]

untradeable_holiday_items.rs2:

New file, as there doesn't seem to be anywhere else appropriate. Any suggestions welcome. It's in data\src\scripts\player\scripts which also contains pickup.rs2, cracker.rs2, which are semi-related and is personal to the player. Is there a better place for this? I considered renaming cracker.rs2 to holiday_items.rs2, and merge together to reduce clutter and cover any future items (rubber_chicken hype??).

The intention is, which is tested as working:

• scythe:

• • If you try pick up a scythe, and you don't already have one, pick it up and set %scythe_unlocked = 1
• • If you try pick up a scythe, and you do already have one, don't allow it

• bunny_ears:

• • If you try pick up bunny_ears, and you don't already them, pick it up and set %bunny_ears_unlocked = 1
• • If you try pick up a bunny_ears, and you do already have one, don't allow it

Example, picking up a scythe after resetting the varp:

Setting these varps means the items are retrievable from Thessalia once you've unlocked them. If they are introduced in any other way, other than picking them up off the ground, these varps need to be set in a different way.

varp.pack / all.varp

I'm not sure how to create a new varp without getting an error. I noticed in a recent PR that existing varps were replaced and used. So for this I replaced varp_7 and varp_8. If this should be done differently please let me know.
Example varp_133 and varp_138 replacement: 7d2c20a#diff-9073420bf978748137737c1955094de93363739ad59d436e43a8165cc6fa34dd

which is why I used varp_7 and varp_8

thessalia.rs2:

Dialogue is different in RSC, but the rest of the dialogue currently matches OSRS so I went with that:
