Fix: Additional onChange deprecation warnings

- Fixed remaining onChange(of:perform:) calls that used explicit 'perform:' label
- Updated onChange calls with capture lists to use new two-parameter syntax
- Simplified capture list patterns as new onChange provides both old and new values

Files fixed:
- WorkspacePanelTabBar.swift
- EditorTabButtonStyle.swift
- EditorTabs.swift (2 instances)
- ExtensionsListView.swift

All onChange deprecation warnings now resolved.
