Update Buddy CI environment variables in README

[czuli]

This PR updates the Buddy CI documentation to reflect the current support for environment variables in Pull Request builds. Buddy now provides the necessary environment variables to determine the source and target branches, enabling accurate detection of branch and prBranch properties by env-ci.

Changes:

• Updated the supported CI table for Buddy.
• Revised the explanatory text to reflect the availability of BUDDY_EXECUTION_PULL_REQUEST_HEAD_BRANCH and BUDDY_EXECUTION_PULL_REQUEST_BASE_BRANCH.

References:

• Buddy Documentation

Hi @travi

I've resolved the issues mentioned in the review comments. Can you please take another look and let me know if there's anything else needed to get this PR merged?

Thank you!

[travi]

thanks for the updates @czuli. this is looking good. we'll need to also update the tests that correspond to your code changes. you can reference the existing tests for that file and others to get an idea of how we verify these behaviors. as you can see, the ci workflow currently fails without those updates. could you look into updating those tests as part of this change?

keep in mind that you can run npm test locally to run all of the verification that runs in the ci workflow before pushing changes to the branch here on github.
