Template Annotation

I love the new missing-fields diagnostic! It is super helpful to guarantee safety especially for function arguments (though its usefullness in my repo has stagnated slightly due to https://github.com/LuaLS/lua-language-server/issues/2214)

However, it does come into conflict with something I do in a few places where I specifically set a type annotation for the autocomplete where the data in the table is initialized later in a meta_table (or the data is only every accessible through the meta_table).

---@type WeaponsUnitData
Weapons.unit = {}

setmetatable(Weapons.unit, Metatable.unit_metatable())

With the new missing-fields diagnostic I get a warning here, that Weapons.unit doesn't contain all of the fields on WeaponsUnitData. I was wondering with the missing-fields diagnostic we could get a ---@template annotation which could describe the shape of a table without having to define all of the fields on it. (As a cleaner alternative to having to do ---@diagnostic disable-next-line: missing-fields in a bunch of places). I am sure other people were also using tables in other weird ways before as well, this would allow an easy transition for them.

Bắt đầu với chẩn đoán missing-fields hiện có và phần xử lý chú thích liên quan đến ---@type. Xác định cách một chú thích ---@template có thể mô tả cấu trúc của một bảng mà không yêu cầu mọi trường, sau đó xác minh rằng ví dụ sử dụng Weapons.unit không còn tạo ra cảnh báo, trong khi các kiểm tra trường bị thiếu thông thường vẫn được giữ nguyên.
