`[meta]` annotations should be loaded instead of just reading the file

Nobody has claimed this yet.

### How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

MacOS

### What is the issue affecting?

Annotations, Libraries

### Expected Behaviour

```json

"codestyle": "Error",
"duplicate": "Hint",

],
"diagnostics.globals": [

],
}

```

```lua
local stringio = require("pl.stringio")
```

`stringio` should use the definition from `meta`

### Actual Behaviour

it reads the real `pl.stringio` and uses that (which does have't luaLS annotations, etc)

### Reproduction steps

1. Download and load penlight into a directory
2. Add the penlight addon
3. `require` a penlight file

### Additional Notes

_No response_

### Log File

[file_Users_frityet_Documents_ChatGPT-Plugins_Lua.log](https://github.com/LuaLS/lua-language-server/files/12778338/file_Users_frityet_Documents_ChatGPT-Plugins_Lua.log)

Start by tracing how require("pl.stringio") resolves the penlight addon and how [meta] annotations are handled, comparing that path with the real pl.stringio file. Done means the require uses the definition from meta annotations, including their LuaLS annotations, rather than the unannotated runtime file.
