docs: fix missing code in getting_started

[seflue]

The code example missed the .send() call and the necessary import.

Hi @seflue, thanks for taking the time to make this PR. Actually in the main branch, the code shown in the examples are valid with simply awaiting the .tell() call directly. This is thanks to PR #72 which implements IntoFuture for requests, which is the same behaviour as .send().await, but with less boilerplate.

This will be available in the next release of Kameo :)

Hi @tqwewe, thanks for the quick reaction. I see, your library is progressing quickly. Is it possible to read the online version of the docs bound to a specific version? I appreciate good documentation and I assume, that it took you quite some effort to write the book. So the motivation for my PR was to not let newcomers run into an issue with the very first example. Is there another way I can help you to keep code and docs aligned?

The docs.rs page will show the docs per version. In terms of the kameo book, sadly there's not a user friendly way to do so. You can however specify a commit/branch/pr by appending ~ to the url of the kameo book. For example https://docs.page/tqwewe/kameo~4a551c31b318623301170941f9f2f27e1e4f9c97

Thank you for your offer to help with documentation, it's definitely something important but also time consuming. I've tried to keep up with all of it, and have recently updated lots of the code docs, so I'm not sure where exactly documentation might be lacking currently. However if you do find anything that can be improved, I'd be happy to review and merge any other PRs
