Feature Request: Deprecate fields and parameters

[Rouneq]

Could really use a clean way to mark specific field and parameters as deprecated. Currently I'm adding @**[DEPRECATED]** to the start of the comments for the field/parameter, but this doesn't change the name with a strike-through (as happens with functions).

You can use ---@deprecated for field. But there is no way for parameter.

You can use ---@deprecated for field.

---@class foo
---@deprecated
---@field example string
foo = {}
