No suggestions for `@spec`ed function params

### Environment
Elixir & Erlang versions (elixir --version):
```
Erlang/OTP 26 [erts-14.2.5.4] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit:ns]
Elixir 1.17.3 (compiled with Erlang/OTP 26)
```
VSCode ElixirLS version: `v0.24.2`
Operating System Version: `Ubuntu 22.04.5 LTS`

### Troubleshooting

- [x] Restart your editor (which will restart ElixirLS) sometimes fixes issues
- [x] Stop your editor, remove the entire `.elixir_ls` directory, then restart your editor

### Details

Given this code:
```elixir
defmodule MyMod do
@type t :: %MyMod{
id: pos_integer(),
name: binary()
}
defstruct id: 0,
name: ""

@spec hello1(person :: MyMod.t()) :: MyMod.t()
defp hello1(person) do
IO.inspect(person)
end

@spec hello2(person :: MyMod.t()) :: MyMod.t()
defp hello2(%MyMod{} = person) do
IO.inspect(person)
end

@spec hello3(person :: MyMod.t()) :: MyMod.t()
defp hello3(person) do
p1 = hello1(person)
IO.inspect(p1)
end

def say_hello() do
person = %MyMod{
id: 123,
name: "Bob"
}

hello1(person)
hello2(person)
hello3(person)
end
end
```
#### Problem
Autocomplete/suggestions for the `person` variable do **not** work in the `hello1()` function

#### Expected result
Autocomplete/suggestions should work for the `person` variable in `hello1()` the same way they work in the `hello2()` function

#### Relevant info
Strangely enough, suggestions work for the `p1` variable in the `hello3()` function
