fix: remove time argument to accept-process-output

Setting the time argument causes the command execution to fail for long command. This is the result of `tdoe`:

```elisp
Debugger entered--Lisp error: (error "Selecting deleted buffer")
  comint-redirect-preoutput-filter("@\n")
  comint-redirect-filter(comint-output-filter #<process BQN> "@\n")
  apply(comint-redirect-filter comint-output-filter (#<process BQN> "@\n"))
  #f(advice comint-redirect-filter :around comint-output-filter)(#<process BQN> "@\n")
```

By removing it, the error disappears.
