--test-options are split wrong

**Describe the bug**
cabal's test-options botches the arguments before it passes them to the test executable

**To Reproduce**
Clone cabal repo, and run the following command

```
cabal v2-test integration-tests2 --test-options '-p "find root"'
```
it should work fine, however the below command doesn't

```
cabal v2-test integration-tests2 --test-options "-p 'find root'"
```

**Expected behavior**
Both methods of passing the arguments should work.

**System information**
- Operating system: nixos
- `cabal`, `ghc` versions: 3.6.2.0, 8.10.7

**Additional context**
Did some investigation, and that the bug is in the `splitArgs` function
```haskell
> splitArgs "-p 'find root'"
["-p","'find","root'"]
```
