perf(kubectx)!: load context asynchronously (#13825)

Browse Source 
BREAKING CHANGE: `kubectx_prompt_info` uses the async prompt API by default on supported zsh versions. Set async-prompt to no for synchronous behavior, or force it when calling it through a wrapper function. See the plugin README for details.

The context is loaded asynchronously on supported versions of zsh so that
`kubectl` does not block the prompt. To restore synchronous behavior, add this
before Oh My Zsh is sourced:
```zsh
zstyle ':omz:alpha:plugins:kubectx' async-prompt no
```
If your theme calls `kubectx_prompt_info` indirectly through another function,
force registration of the async handler instead:
```zsh
zstyle ':omz:alpha:plugins:kubectx' async-prompt force
```
