chore: Use 'latest' tag for Qdrant module (#815)

Switches the Qdrant image tag to `latest` by default. This makes it
easier to use new features like the [Batch Search
API](https://qdrant.tech/documentation/concepts/search/#batch-search-api)
without manually updating the version.

The latest version is 1.13.5 as of today. You can still override the
image if needed, but this keeps things simple and up to date by default.
