fix: Do not override GITHUB_TOKEN env var, fixes #27

[github-actions]

Issues Identified:

1. README.md - Typo Correction:

   • The change in README.md corrects a typo where system prompt was incorrectly used instead of user prompt. This is a good change as it aligns the documentation with the intended meaning.

2. review.nu - Unnecessary Environment Variable Assignment:

   • The line $env.GITHUB_TOKEN = $gh_token | default $env.GITHUB_TOKEN? was removed. This could be problematic if the code relies on $env.GITHUB_TOKEN being set elsewhere. If $gh_token is expected to be the primary source for the GitHub token, ensure that it is properly handled in the rest of the code.

Recommendations:

1. README.md:

   • No further action is needed for README.md as the change is correct and improves clarity.

2. review.nu:

   • Ensure Token Handling: Verify that $gh_token is properly passed and used throughout the script. If $env.GITHUB_TOKEN is still required elsewhere, ensure it is set appropriately.
   • Documentation Update: If the removal of the environment variable assignment is intentional, update the documentation to reflect that $gh_token should be used directly instead of relying on $env.GITHUB_TOKEN.

Summary:

• The changes in README.md are correct and improve clarity.
• The removal of the environment variable assignment in review.nu requires careful consideration to ensure it does not break functionality. Ensure that $gh_token is properly handled and documented.
