add retries (#60)

### Summary by OpenAI

**Release Notes**

This pull request adds retry functionality to improve the reliability of
sending messages using the OpenAI API. It includes a new function called
`retry` in the `src/utils.ts` file and modifies the `src/bot.ts` file to
use this function for retrying message sending in case of failure. This
is a "New Feature" that enhances the user experience by reducing the
likelihood of failed message sending.
