Add workflow links to try build started comments

[mostafa630]

This PR introduces support for adding workflow links to the comment that gets created when a try build starts.

Implementation details

Within handle_workflow_started, we now invoke a new function:
add_workflow_links_to_try_build_start_comment.

That function performs the following steps:

1. Retrieve the build using its commit_sha.

2. Find the PR associated with that build.

3. Locate the TryBuildStarted comment for that PR.

4. Fetch the workflows linked to the build.

5. Retrieve the comment’s current content (via GraphQL).

6. Append the workflow links to the content to generate the updated version.

7. Update the comment with this new content.

tests

getting the comment content and updating it require us to extend the github.rs mock file to handle them
so I change the logic to check if the request is query or mutation
then handle each case based on operation name

Hi, this looks great, thank you! I left some small comments, but pretty much the only thing left is to write a test. Let me know if you want help with that, I can push the test to this PR if you want.

thanks a lot for the review and feedback , I’ve made the suggested changes. I’m not fully sure about the tests and test infra, so it would be great if you could add them. Thanks again for your support!

Added the tests, and did some test refactoring before that. Thank you, this looks pretty nice!

There were some bugs in the GraphQL calls that I found when testing this on a live repository. But at least it forced me to implement proper GraphQL error handling :) I fixed the bugs and the tests and it seems to work great now, thanks!
