chore: update JS/TS example in README (#898)

- The JS/TS library actually expects named parameters via an object in
`.createTable()` rather than individual arguments
- Added example on how to search rows by criteria without a vector
search. TS type of `.search()` currently has the `query` parameter as
non-optional so we have to pass undefined for now.
