update examples with latest request-converter

[miguelgrinberg]

This PR refreshes all the language code examples. To ensure that always the latest request-converter is used for this task, I've also added an npm update @elastic/request-converter to the make generate-language-examples task.

Following you can find the validation changes against the target branch for the APIs.

No changes detected.

You can validate these APIs yourself by using the make validate target.

could we merge #5780 before? I've fixed some examples

[miguelgrinberg]

This PR is now updated. I noticed that at some point the examples were re-generated with an older request converter, because a bunch of them are incorrect. These are all fixed in this PR as well.

[miguelgrinberg]

Once we merge the Java PR in the request converter we will be able to remove the JavaCaller code and run the Java conversions in the same way as the other languages.

@miguelgrinberg LGTM, but are we ready to merge the other PR?
