inject-field diagnostics when defining LOVE callbacks.

Nobody has claimed this yet.

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

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Windows

### What is the issue affecting?

Diagnostics/Syntax Checking, Libraries

### Expected Behaviour

This should be clean.

```lua
local love = require("love")

function love.load() -- no diagnostics here
end
```

### Actual Behaviour

```lua
local love = require("love")

function love.load() -- Fields cannot be injected into the reference of `love` for `load`. To do so, use `---@class` for `love`. (inject-field)
end
```

### Reproduction steps

1. Ensure to have LOVE Definition addon.
2. Create new `main.lua` with content above.

### Additional Notes

LOVE addon `@class` is not defined with `(exact)`.

### Log File

[file_d%3A_Data_Development_love-11.3-win64_inochi2d.log](https://github.com/LuaLS/lua-language-server/files/12561875/file_d.3A_Data_Development_love-11.3-win64_inochi2d.log)

Reproduce the diagnostic in a new main.lua using the LOVE Definition addon and the shown love.load callback, then review the linked log for context. The work is done when this valid LOVE callback no longer reports an inject-field diagnostic while diagnostics remain available for genuine cases.
