completion: install completers to conventional locations...

completion: install completers to conventional locations Installs the bash and zsh completers to the convential locations so they will automatically be picked up without user intervention. The zsh completer on Debian is still installed to vendor-completions to match their policy. bash: https://github.com/scop/bash-completion#faq zsh: https://github.com/zsh-users/zsh/blob/57305cf245853b8b30895b41a90142dffab97e38/INSTALL#L254 Debian zsh: https://salsa.debian.org/debian/zsh/-/blob/5086b5356abcef8849dc8a09902b7c55f01db3c0/debian/README.Debian#L73
