- full diff: https://github.com/spf13/cobra/compare/v1.7.0...v1.8.0

Release notes highlights:

Features

- Support usage as plugin for tools like kubectl - this means that programs
  that utilize a "plugin-like" structure have much better support and usage
  (like for completions, command paths, etc.)
- Move documentation sources to site/content
- Add 'one required flag' group - this includes a new MarkFlagsOneRequired API
  for flags which can be used to mark a flag group as required and cause command
  failure if at least one is not used when invoked.
- Customizable error message prefix - This adds the SetErrPrefix and ErrPrefix
  APIs on the Command struct to allow for setting a custom prefix for errors
- feat: add getters for flag completions
- Feature: allow running persistent run hooks of all parents
- Improve API to get flag completion function

Bug fixes

- Fix typo in fish completions
- Fix grammar: 'allows to'
- powershell: escape variable with curly brackets
- Don't complete --help flag when flag parsing disabled
- Replace all non-alphanumerics in active help env var program prefix
