argopy notebook ok?

The [argopy notebook](https://euroargodev.github.io/ArgoData.jl/dev/Argo_argopy.html) was recently updated to the new interface that is based on `PythonCall.jl` and `CondaPkg.jl` (in `ArgoData.jl v0.1.23` ).

There are a few ways the [Pluto](https://plutojl.org) notebook could be improved without too much work probably. For example, a couple other functionalities of `argopy` could be demonstrated (code cells) and a bit more information on `argopy` added (markdown cells).

@gmaze , are you able to run [the notebook](https://raw.githubusercontent.com/euroargodev/ArgoData.jl/refs/heads/master/examples/Argo_argopy.jl)?
