Enhance PR test workflow with concurrency and path ignore settings

This commit updates the PR test workflow by adding concurrency management to cancel in-progress workflows for the same branch. Additionally, it modifies the branch specifications to remove spaces and introduces a paths-ignore directive to exclude changes in the "assets/**" directory from triggering the workflow. These changes aim to streamline the testing process and improve efficiency.
