discard-returns warning is not triggered in while/repeat loops

Nobody has claimed this yet.

Annotations

### Expected Behaviour

@nodiscard annotated functions should always trigger the `discard-return`s warning in any context.

### Actual Behaviour

`discard-returns` does not trigger in _while_ and _repeat_ loops.

### Reproduction steps

```lua

---@nodiscard
local function bar()
--@nodiscard annotated function
end

while true do
bar() --< this DOES NOT trigger no-discard
break
end

repeat
bar() --< this DOES NOT trigger no-discard
break
until true

bar() -- < this DOES trigger no-discard

for index, value in ipairs({}) do
bar() -- < this DOES trigger no-discard
end
```

Reproduce the issue in the Visual Studio Code extension using the Lua snippet from the report, then trace how the discard-returns warning handles while and repeat loops compared with direct calls and for loops. Done means @nodiscard calls in both loop forms trigger the warning consistently with the other contexts.
