zsh completion script should not assume complete command exists

[bobtiernay-okta]

After recently upgrading my macOs to Mojave, I found out that my Picocli autocomplete script stopped working with the following error:

.my-completion.sh:2899: command not found: complete`

To solve the problem I needed to add the following prior to running the script:

autoload bashcompinit
bashcompinit

On further inspection, I noticed https://picocli.info/autocomplete.html#_install_completion_script illustrates in passing that this is required. I'm wondering if it makes sense to add that to the generated script if complete isn't defined. That would allow the instructions for bash and zsh to be the same.

I’m open to any improvements.
Do you think you can provide a pull request?

The generated completion script itself now enables bash completion in zsh.

That means it is no longer necessary to run the below commands in ZSH before sourcing the completion script:

autoload -U +X compinit && compinit
autoload -U +X bashcompinit && bashcompinit

Can you verify?
