vendor: github.com/spf13/cobra v1.1.1

v1.1.1:

- Fix: yaml.v2 2.3.0 contained a unintended breaking change. This release reverts
  to yaml.v2 v2.2.8 which has recent critical CVE fixes, but does not have the
  breaking changes.
- Fix: correct internal formatting for go-md2man v2 (which caused man page
  generation to be broken).

v1.1.0:

- Extend Go completions and revamp zsh comp
- Add completion for help command
- Complete subcommands when TraverseChildren is set
- Fix stderr printing functions
- fix: fish output redirection
