Support for pseudo terminal on Web

[bummoblizard]

1. Create a pseudo terminal in a web extension

const writeEmitter = new vscode.EventEmitter<string>();
const pty: vscode.Pseudoterminal = {
  onDidWrite: writeEmitter.event,
  open: () => writeEmitter.fire('\x1b[31mHello world\x1b[0m'),
  close: () => {}
};
vscode.window.createTerminal({ name: 'My terminal', pty });

2. yarn web
3. Error: Could not create terminal when process support is not registered

From my understanding, terminal is disabled on web due to the lack of process support. Should this affect the use of pseudo terminal as well? In my use case, I would like to create a fake terminal in my web extension.

The Pseudoterminal API will work when actually running in web like Codespaces, just not when running yarn web as it's a stripped down version of the server.

Reopening as live share web would like this

Hi, @Tyriar , is it scheduled to be fixed soon :) ?

[Tyriar]

We'll try squeeze this into the iteration for next week

Fixed showing the select default shell command which doesn't work without an ext host while working on this: #118978

@setaskin this should land in tomorrow's insiders build, if you could test whether this works for you sometime this week (ideally) that would be great!

@Tyriar that is awesome!, I will test as first thing tomorrow. Thank you very much

@Tyriar , I just tested with insiders. They are working great. Thanks again.
