ENH: Use common file for GPU admonition

[mmcky]

This PR moves the GPU admonition to _admonitions/gpu.md

• wealth_dyanmics
• kesten_processes

@jstac do you agree with this approach.

The alternative would be to add a more subtle tag such as in QuantEcon/lecture-python-programming#255 (comment)

fixes QuantEcon/meta#75

@jstac if you think this is a better setup I can merge and update the QE manual.

@mmcky Thanks. These lectures are having JAX stripped out so I think it's correct to remove the tag. (I'm not sure why we would want a more subtle one if the JAX code is being removed? Sorry if I've misunderstood.)

[mmcky]

@jstac this is essentially a proof of concept to setup quantecon standard admonitions such as the GPU message for files that make use of the gpu. Indeed -- this is getting migrated to lecture-jax but this is a style question for you -- so we only have one place to update the admonition text that is shared across files.

If you like this style using import I will update our style guide with default locations for _admonitions in lectures.

[jstac]

Yes, good plan @mmcky, thanks!

Note that @Smit-create has already removed JAX from one of these lectures though --- see #335

It might be gone from the other one too --- I can't remember.

[mmcky]

Roger that. Thanks @jstac
