Changes

This PR removes the quarantine section from both README files since v0.1.5 supports Apple notarization.

Updates:

• ✅ Removed "Disable the quarantine attribute" section from both README.md and README_zh.md
• ✅ Renumbered subsequent sections (3→2, 4→3, 5→4, 6→5)
• ✅ Added note that v0.1.5+ supports Apple notarization and no longer requires disabling quarantine
• ✅ Added reference to previous documentation for users on older versions
