Describe the bug

For commands like kubectl that aren't natively supported by Warp, the tab completion should defer to the shell completion.

When running in a normal terminal emulator running something like kubectl <tab> will give a list of supported operations and even stuff like kubectl describe pod <tab> will show a list of pods.

With Warp this doesn't happen and instead, it just shows a list of files in the working directory. This is super annoying and makes it very hard to use. I find myself having to switch between 2 terminals because of this.

I've also noticed this happen with other commands like Skaffold. I think it would be unreasonable to expect native support for every command, but having a way to fall back to Shell completion would be nice.
