raulcd opened a new pull request, #47474: URL: https://github.com/apache/arrow/pull/47474
### Rationale for this change The Release suffered some changes around automated signature and verification tasks that were not reflected on the Release Management guide. The C# implementation has also been moved to it own repository, I took the time to reflect that change on the Release Management guide too. ### What changes are included in this PR? Update release management guide to cover automated signing of source artifact and automated trigger for verification tasks. Remove C# from the Release management guide and post-steps. ### Are these changes tested? Not necessary but I'll trigger preview docs. ### Are there any user-facing changes?
