Copilot 1ac68f65bf Python: Fix RedisContextProvider for redisvl 0.14.0 by using AggregateHybridQuery (#3954) 
* Initial plan

* Fix: Replace alpha with linear_alpha in HybridQuery for redisvl 0.14.0 compatibility

Co-authored-by: markwallace-microsoft <127216156+markwallace-microsoft@users.noreply.github.com>

* Address code review: Improve test readability and add explanatory comment

Co-authored-by: markwallace-microsoft <127216156+markwallace-microsoft@users.noreply.github.com>

* Add CHANGELOG entry for redisvl 0.14.0 compatibility fix

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Use AggregateHybridQuery instead of HybridQuery for backward compatibility

Replace HybridQuery with AggregateHybridQuery to preserve existing functionality that works with older Redis versions. The new HybridQuery in redisvl 0.14.0 requires Redis 8.4.0+ and uses a different API, while AggregateHybridQuery maintains compatibility with the original implementation.

* Fix test to use linear_alpha parameter matching _redis_search implementation

The test was passing alpha as a keyword argument to _redis_search(), but the
method uses linear_alpha to match the redisvl 0.14.0 AggregateHybridQuery API.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Fix pyright error: use alpha parameter matching AggregateHybridQuery API

AggregateHybridQuery expects 'alpha', not 'linear_alpha'. Updated the
_redis_search method parameter and the test accordingly.
