Really deprecate dvcorg/cml-py3

[DavidGOrtega]

• mention the old image is deprecated in the readme & website?
• update youtube videos?
• look for popular external blogs?

At LEAST our deprecated image dvcorg/cml-py3:latest does not contain CML.
The biggest problem is that we deprecated this image when many resources and tutorials still uses it.

Run cml --version
/__w/_temp/269a2252-363f-4a5e-9c83-9393827d7f47.sh: 1: /__w/_temp/269a2252-363f-4a5e-9c83-9393827d7f47.sh: cml: not found
Error: Process completed with exit code 127.

In fact, cml-py3 images do include an old version of CML that predates #703 and the unified cml command; running cml-send-comment --version for example should work as expected.

I wouldn't update those deprecated container images, as per #383 (comment). Instead, this should become a documentation issue to fix all the references to deprecated container images.

We need to avoid this discouraging UX

🔔 @iterative/cml, worth addressing the second point?
