draw_bounding_boxes and save_image require different input dtype

[SeucheAchat9115]

Hi, when using draw_bounding boxes an image torch.tensor needs to be converted to uint8 dtype because the function expects that dtype. When inserting the image with drawn boxes to save_image, it needs to be converted back to float32 dtype. Can this be changed to easily insert the images to both functions without type conversion?

Thanks for the report @SeucheAchat9115 , we should add float32 support to the draw_* utils. Would you like to submit a PR for that?

I think I have no capacity to do that.

Hey @NicolasHug

Can you please re-open this issue? I have lined up a new PR #8276

Thank you!
