Request for more examples

[MarcoGorelli]

For the dataframe Api we currently have a folder with some examples https://github.com/data-apis/dataframe-api/tree/main/spec/API_specification/examples

Just 2 at the moment

I'd like to request that people add some more, in order to capture the kinds of things they intend to use the dataframe Api for

@kkraus14 and @shwina I've seen you both make examples of dataframe agnostic functions in calls - if you could add such examples to the repo this will make conversations going forwards much easier

Thanks!
