[Bug]: [Python] BatchElements and ToList website examples are broken

[hjtran]

What happened?

https://beam.apache.org/documentation/transforms/python/aggregation/batchelements/
https://beam.apache.org/documentation/transforms/python/aggregation/tolist/

These were introduced by #30788

I checked in Beam Playground with print(beam.__version__) and it looks like it's' running 2.56 which is when these examples were added. I'm not sure if maybe there's an extra step somewhere to update some database of examples used for the website?

@damccorm You helped me with the original PR. Any idea what's missing here?

I think I already fixed broken examples here: #31647.
I guess there is need to update website

[tvalentyn]

Also came across this issue; to my knowledge, the website is are being updated regularly, most likely additional changes are necessary

[tvalentyn]

@Amar3tto For example, fixes in #31778 point to currently working examples

The website uses beam 2.56.0 which doesn't have transforms with the correct names

[damccorm]

I don't think the problem is with the website, it is with the playground itself. If you click through to playground, the same problem exists - https://play.beam.apache.org/?path=SDK_PYTHON_ToList&sdk=python

There was a issue in inline yaml for prod playground deploy. That is fixed and is running 2.59 now

[Amar3tto]

The version has been updated, but the examples are still broken. We are working on it.

[hjtran]

Thanks for the update!

[Amar3tto]

Looks like all examples are fixed

[hjtran]

Confirmed they look good. Thanks for the fix!!

[tvalentyn]

Thanks all!
