Summer 2022 Release

Some exciting changes make their way to Cobra! Command completions continue to get better and better (including adding --help and --version automatic flags to the completions list). Grouping is now possible in your help output as well! And you can now use the OnFinalize method to cleanup things when all "work" is done. Checkout the full changelog below:
