fix(ci): improve concurrency grouping in quality workflow

[MaxLee-dev]

Description of Changes

Improve the concurrency grouping in the quality workflow by using github.head_ref || github.ref instead of just github.ref. This ensures that:

• For pull requests, workflows are grouped by PR branch name (head_ref)
• For direct branch pushes, workflows fall back to the ref

This prevents multiple workflow runs from different commits in the same PR from running simultaneously, improving CI efficiency.

Checklist

• The PR title follows the Conventional Commits convention. (e.g., feat, fix, docs, style, refactor, test, chore)
• I have performed a self-code review.
• I have followed the project's coding conventions and component patterns.

Similar to quality checks, when a new commit is pushed to packages/core, previous tests become obsolete, so concurrency is added.
