Fix multiarq build (#240)

* 🔧 (extension-attach-artifact-release.yml): use matrix.os value for runs-on field to allow flexibility in choosing operating system for the workflow job.

* 🔧 (pro-extension-test.yml): make the workflow run on the specified operating system defined in the matrix configuration for flexibility and customization

* 🔥 (DS_Store): remove .DS_Store file from the repository to avoid unnecessary clutter and prevent accidental commits of binary files
