Allow local server option to code tunnel command

[MiguelRodo]

I've been using code-server serve-local instead of accessing as accessing the remote machine via vscode.dev is slow for me (reported here: #7242). I see that we are to switch over from code-server to code tunnel, as announced in the latest blog post. But, from examining code tunnel's help file, I can't see any option to use a local server instead of vscode.dev.

So, I'd like to continue being able to use the local server. If it's already easily doable as before, then I'd like to know how. Otherwise, I'd like it to be added to code tunnel's functionality. Thanks!
