[Documentation]: Documentation on fixing GitHub issues with OpenDevin

[neubig]

It would be nice to have better documentation on fixing github issues with OpenDevin. This should be added to the documentation in the docs/ directory in the appropriate place.

A first draft of the required documentation is below between the lines:

---

To fix an issue on OpenDevin, send a prompt like:

Please fix a github issue according to the following procedure:
1. Read the issue on https://github.com/OpenDevin/OpenDevin/issues/1611
2. Clone the repository and check out a new branch
3. Based on the instructions in the issue description, modify files to fix the issue
4. Push the resulting output to github using the GITHUB_TOKEN environment variable
5. Tell me the link that I need to go to to send a pull request

Before you run OpenDevin, you can do

export SANDBOX_ENV_GITHUB_TOKEN=XXX

where XXX is a github token that you created that has permissions to push to the OpenDevin repo. If you don’t have write permission to the OpenDevin repo, you might need to change that to:

4. Push the resulting output to my fork at https://github.com/USERNAME/OpenDevin/ using the GITHUB_TOKEN environment variable

where USERNAME is your github username.
