Skip previews on PRs from forks

[AlexITC]

Due to security constraints, there is no way to generate previews from forks, let's skip the job instead of letting it fail.

Screenshots/Recordings:

Codepreview step is not failing anymore:

On PRs from the same repo, codepreview runs as expected:

📝 Walkthrough

Walkthrough

The GitHub Actions workflow .github/workflows/codepreview.yml adds a skip-if-fork job that prints skip messages for forked PRs. The existing preview job now has an if guard so it runs only for non-pull_request events or PRs where the head repo matches the base repo.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow .github/workflows/codepreview.yml	Added skip-if-fork job that runs for forked pull requests and prints skip messages. Modified preview job to include `if: ${{ github.event_name != 'pull_request'

Poem

🐰 I nibble on branches and check every fork,
If the head's not at home, I kindly abort,
A soft little hop, a message I sing,
Preview waits for the repo where it belongs,
Hooray for safe runs and neat CI springs!

In @.github/workflows/codepreview.yml:
- Line 23: The workflow conditions reference github.event.pull_request.* even
when the workflow can be triggered by push, causing incorrect job skipping;
update the conditional expressions used in the preview/skip-if-fork job(s) to
first check the event type (e.g., ensure github.event_name == 'pull_request')
before accessing github.event.pull_request, for example by combining the checks
so the existing github.event.pull_request.head.repo.full_name ==
github.repository (and the similar check on Line 71) only runs when
github.event_name == 'pull_request'.
