fix: remove edited type trigger from enforce-release-source ci

[trueberryless]

🧭 Context

CI on main is (seemingly randomly) failing because the enforce-release-source action gets cancelled. This PR aims to fix this issue.

📚 Description

To my understanding, the problem is cause because merge queues quickly add commits to main, which causes two things:

1. the commit from main lands in the automatically generated next release PR, which causes the enforce-release-source action to trigger because of the synchronize type
2. the release-pr workflow updates the PR description, which causes the enforce-release-source action to trigger a second time within a short time frame because of the edited type

This results in two workflow runs getting triggered and one getting cancelled because both events trigger quickly after each other. Therefore, removing the edited type should resolve the issue, as it removes one of the concurrent runs. Since an edit of the PR description does not include target branch changes, removing the edited type would be my solution. I also explicitly set cancel-in-progress to false to avoid future confusion.

So I think this cancellation happens seemingly random because workflows just do not take the same time always, resulting in the cancellation sometimes happening because of timing reasons, and sometimes not.

This is just how I understood it after debugging for the last 2 hours. I would really appreciate another four eyes on my deduction.

📝 Walkthrough

Walkthrough

This PR updates the enforce-release-source GitHub Actions workflow to trigger on PR commit synchronizations (synchronize) instead of PR edits, and it adds cancel-in-progress: false to the workflow concurrency configuration.

Changes

Workflow configuration updates

Layer / File(s)	Summary
Trigger event types .github/workflows/enforce-release-source.yml	Replaced pull_request_target.types entry edited with synchronize so the workflow runs on commits pushed to a PR.
Concurrency configuration .github/workflows/enforce-release-source.yml	Added cancel-in-progress: false beneath the existing concurrency.group setting to prevent automatic cancellation of in-progress runs.

❌ Failed checks (1 error)

Check name	Status	Explanation	Resolution
Title check	❌ Error	The title states 'remove edited type trigger' but the PR objectives describe removing both the edited trigger AND the concurrency block, with the concurrency block being the primary fix.	Update the title to accurately reflect both key changes: 'fix: remove concurrency block and edited event trigger from enforce-release-source ci' or clarify if only the edited trigger removal is the main concern.
