lancedb-gatefixer[bot] c7cb0b9afa docs(python): clarify threading on two-CPU containers (#3807)
## Summary

- document that current LanceDB releases use one compute worker without
warning on two-vCPU containers
- distinguish compute-worker tuning from storage I/O concurrency
- direct users of affected LanceDB 0.21.1 installations to upgrade and
link the current threading guidance

## Root cause

The Lance version bundled with LanceDB 0.21.1 warned whenever the
detected CPU count was less than or equal to its default two-core I/O
reservation. A two-vCPU deployment therefore emitted the warning on
every query even though falling back to one compute worker was the
intended behavior. Lance fixed that warning condition upstream in
lance-format/lance#3710, and LanceDB current main already pins a version
containing the runtime fix; the Python package documentation did not
explain the corrected behavior or the distinct thread controls.

## Validation

- `git diff --check`
- verified the linked Lance threading-model documentation returns HTTP
200

Fixes #2326
