Fix --width --height type parsing on opencv and intelrealsense scripts

[apockill]

Super minor PR. I had to set --width and --height on the opencv script when testing things out, and found that it wasn't working since it was trying to give cv2 caps a string.

Thanks!

If you have time, could update intelrealsense.py as well?

lerobot/lerobot/common/robot_devices/cameras/intelrealsense.py

Lines 536 to 547 in 4abf87e

	parser.add_argument(
	"--width",
	type=str,
	default=640,
	help="Set the width for all cameras. If not provided, use the default width of each camera.",
	)
	parser.add_argument(
	"--height",
	type=str,
	default=480,
	help="Set the height for all cameras. If not provided, use the default height of each camera.",
	)
