Disable IDE integrations

[mikucat0309]

In https://github.com/loft-sh/devpod/blob/main/pkg/ide/ideparse/parse.go

It seems that Devpod always open an IDE, but I just need the CLI environment which already setup in the Dockerfile.

I know we can just close the default open-vscode in browser, but if we can skip start it that will be perfect!

You can do devpod up --ide none .... I use that so spin the container and then ssh into to run nvim.
