Fix wandb tensorboard bug of not logging metrics

[vwxyzjn]

On windows, the wandb's tensorboard integration could break, not logging anything as shown below:

This can be fixed by

        run = wandb.init(
            project=args.wandb_project_name,
            entity=args.wandb_entity,
            sync_tensorboard=True,
            config=vars(args),
            name=experiment_name,
            monitor_gym=True,
            save_code=True,
        )

to

        run = wandb.init(
            project=args.wandb_project_name,
            entity=args.wandb_entity,
            # sync_tensorboard=True,
            config=vars(args),
            name=experiment_name,
            monitor_gym=True,
            save_code=True,
        )
        wandb.tensorboard.patch(save=False)

So basically comment out # sync_tensorboard=True, and add wandb.tensorboard.patch(save=False)

This seems to be a similar problem to wandb/wandb#2772 except in our case this only happens at windows.
