text: Title: Add an easy option to log to terminal and a file
  Body: the logging tutorial suggests using `>` for redirection but then we lose terminal logs. we should modify the CLI so users can send the logs to a file. e.g.,
  
  ```
  # set log level and log to the terminal
  ploomber build --log info --log-file my.log
  ```
  
  
  ```
  # set log level, adding --log-file logs to the terminal and to a file
  ploomber build --log info --log-file my.log
  ```
