Feature Request/How-to: Inlined parameter annotation

I'd like to be able to do inlined type annotation for parameters. It doesn't currently seem to be possible. What I mean is, instead of this:

---@param key                       unknown
---@param callbackFn                fun(Hook, ...):any
---@param priority?                 number
---@param hostTableToHook?          table
---@param defaultNativeBehavior?    function
---@param hookedTableIsMetaTable?   boolean
function Hook.basic(key, callbackFn, priority, hostTableToHook, defaultNativeBehavior, hookedTableIsMetaTable)
    return Hook.add(key, callbackFn, priority, hostTableToHook, defaultNativeBehavior, hookedTableIsMetaTable, true)
end

I'd like to be able to do this:

function Hook.basic(
    key,                    ---@param unknown
    callbackFn,             ---@param fun(Hook, ...):any
    priority,               ---@param? number
    hostTableToHook,        ---@param? table
    defaultNativeBehavior,  ---@param? function
    hookedTableIsMetaTable  ---@param? boolean
)
    return Hook.add(key, callbackFn, priority, hostTableToHook, defaultNativeBehavior, hookedTableIsMetaTable, true)
end

This would cut down on the boilerplate a bit and make the code cleaner.

Start by locating the language server's parsing and tests for function parameters and existing inline annotations. Compare those paths with the two syntax examples in this issue; done means inline parameter annotations are accepted, interpreted with the shown optional and function types, and covered by tests.
