test(react-tabs): Use valid nomemory focusgroup token in TabList example

[Copilot]

The TabList base-hook test continued to demonstrate the unsupported no-memory focusgroup token. Update the example and its inline snapshot to use the valid spelling.

• React Tabs
  • Replace no-memory with nomemory in the focusgroup assignment and rendered snapshot.

state.root.focusgroup = `tablist ${state.vertical ? 'block' : 'inline'} nomemory wrap`;
