ee7fa43d - fix: swapped _R_co and _P to prevent type error. (#20508)

fix: swapped _R_co and _P to prevent type error. (#20508) When loading a pytorch-lightning model from MLFlow, I get `TypeError: Type parameter +_R_co without a default follows type parameter with a default`. This happens whenever doing `import pytorch_lightning as pl` which is done by packages like MLFlow.
