fix: correct screenshot placements and add clarifying captions

- Move query-v2.png to parameterized query section (it shows args/options,
  not the basic listAirlines query)
- Add captions noting _default scope/collection in CRUD screenshots
  should be replaced with inventory/airline
- Add caption noting hotel-index in fts-search-v2.png should be
  replaced with airline-name-index

 > **Why parameterized queries?** Instead of concatenating user input directly into SQL++ strings (which risks injection attacks), Couchbase's `$parameter` syntax sends values separately from the query statement. The plugin passes these through the `args` field in the Data API request body. You can also pass **Query Options** like `{ "readonly": true, "timeout": "30s" }` for additional control.
