I'm not sure we need to be that explicit in the local development tool, but the change seems harmless. We could consider updating other places to be consistent, though:

apps/studio/src/components/content-tab-overview.tsx
apps/studio/src/components/content-tab-import-export.tsx
apps/studio/src/ipc-handlers.ts
apps/studio/src/tests/show-site-context-menu.test.ts
