Barbtail Harpoon Fix

What have you done in this MR?

• Implemented nothing
• Fixed barbtail harpoon being unable to fish sharks (closes #804 (closed))
• Fixed barbarian fishing animation being used when fishing with a barbtailed harpoon

Are there any tricky things testers should keep an eye out for?

• No

• Yes, as follows:

• I have tested these changes thoroughly.

• This requires extra testing due to changes to architecture or other similarly risky changes.

• I used the Thanos Tool for any JSON edits where possible, and have attached screenshots of any changes.
