Mention of deprecated symbols in 101 samples

Hello,
I am starting to learn the libgit2 API and in the first example I wanted to try I stumbled upon git_indexer_progress: https://libgit2.org/docs/guides/101-samples/#repositories_clone_progress.
Unfortunately, this does not appear anywhere in the reference: https://libgit2.org/libgit2/#HEAD/search/git_transfer_progress.
Further investigation showed that it is simply because it is a deprecated name of git_indexer_progress.

So, I will definitely do a PR for this particular instance, but it would be nice to be able to catch all such symbols automatically if possible.

Do you think there would be a reliable way to do so, or we should try to parse the "deprecated" header ?

101 samples page、特に repositories_clone_progress example から始め、そのシンボルを libgit2 reference search と比較してください。deprecated header から deprecated names を確実に検出できるか調査してください。影響を受ける samples が特定され、それらを扱う保守しやすいアプローチが文書化されれば完了です。
