docs: fix 404 vector range query link in docstring (#647)

## Summary
Fixes #622

The `VectorRangeQuery` docstring linked to a stale Redis docs URL that
now returns a 404:

- Old (404):
`https://redis.io/docs/interact/search-and-query/search/vectors/#range-query`
- New (200):
`https://redis.io/docs/latest/develop/ai/search-and-query/vectors/#range-query`

The new URL matches the style already used by the `VectorQuery`
docstring link in the same file.

## Notes
- Docstring-only change; no code behavior is affected, so the commit
carries `[skip ci]`.
