draw_keypoints() float support

[GsnMithra]

Follow-up PR: #8150

Hey there!

I've added functionality to the draw_keypoints() method, allowing it to handle both uint8 and float32 image types. I welcome any feedback you may have on these changes.

Thank you!

Hey @NicolasHug,

Thank you for pointing out my mistakes. While it might be second nature for you to find these bugs, I am still in the learning process. I apologize for making you go through my code once again.

Thanks again.

No problem at all @GsnMithra thank you for the PR
