Ankur Kothari c320635c29 fix use of bash builtin in elvish integration ...

`type` is a bash builtin and should not be used in elvish.

```
Exception: exec: "type": executable file not found in $PATH
  ghostty-integration.elv:120:60-71:   if (and (not $no-sudo) (not-eq "" $E:TERMINFO) (eq file (type -t sudo))) {
  ghostty-integration.elv:38:1-123:1:
```

We can use the elvish `has-external` function instead.
