Make ultralytics code snippet generic (#1101)

Follow-up PR after
#1093 and especially
this thread
#1093 (comment).

I agree with @NielsRogge's point that `ultralytics` _is_ the library
name. Yolov8 or Yolov10 are "just" model names.

> there's no way of knowing which yolo version would it be because
there's no config file.

The solution I suggest in this PR is to use the repo tags instead. I
have checked and all 258 [ultralytics
models](https://huggingface.co/models?other=ultralytics) have a "yolovX"
tag.
~In parallel I suggest to remove the `yolov10` library since code
snippet is now correctly generated for them as well. I have checked and
[29 out of 63 yolov10
models](https://huggingface.co/models?other=yolov10) don't have the
`ultranalytics` tag so they'll loose the code snippet. If we agree on
this solution I'll open PRs on these repos and everything should be
good.~ See below: in the end, I kept `yolov10` but unified the code
snippet generation.

@merveenoyan @NielsRogge @pcuenca let me know what you think. Will this
definitely close the yolo/ultranalytics tags matter ?

**Note:** some models have multiple yolo tags (e.g.
https://huggingface.co/Ultralytics/YOLOv8 has v10, v8, v3, v5, v9). In
that case I suggest to only take the first one (v10 in this case). But
to be honest, this looks more like something to fix in the model's
metadata
