Bug description

Initialising WandbLogger with save_dir=... properly sets the directory for the wandb folder with the logs files. dir= doesn't work and wandb is saved in the os.cwd().

What version are you seeing the problem on?

v2.0

How to reproduce the bug

from lightning.pytorch.loggers import WandbLogger
WandbLogger(project="abc-123", config=vars(args), save_dir=cluster.log_dir, mode=("disabled" if args.debug else "online")))

vs

from lightning.pytorch.loggers import WandbLogger
WandbLogger(project="abc-123", config=vars(args), dir=cluster.log_dir, mode=("disabled" if args.debug else "online")))

yield different results.
