fix: pin Meshery UI to pre-upgrade commit to restore integration test

Meshery UI's master is broken after upgrading to @mui/x-tree-view@v8
(meshery/meshery#18163) which removed the TreeView export, while their
component code still imports from '@mui/x-tree-view/TreeView'.

Pin to the last known-good commit until Meshery UI fixes the migration.
