Resolve "Sweetcorn (bowl) cannot be made from using Cooked sweetcorn on a bowl with knife"

What have you done in this MR?

• Created sweetcorn bowl listener
• Created tuna and corn listener and removed incomplete/incorrect legacy plugin

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.
• I acknowledge that this contribution will be released under the AGPL license.

Testing:

• Sweetcorn bowl is made by using an empty bowl on a cooked sweetcorn (no knife is required). No exp is gained.
• Tuna and corn is made in two different ways and requires 67 cooking to make. 204 exp is gained.

1. Using tuna on sweetcorn bowl. Knife is required.
2. Using cooked sweetcorn on chopped tuna. No knife is required.

• Cooking interface prompts player for how many they wish to make (1, 5, X, All)
