Fix TypeError when parameters=None in query_items

[Nikhil172913832]

Fixes #43662

Ensure parameters=None is treated the same as omitting parameters, preventing TypeError in HTTP request layer.

Description

This PR fixes a TypeError that occurs when parameters=None is explicitly passed to container.query_items() in the Cosmos DB SDK.

Problem:
When users explicitly pass parameters=None to query_items(), the SDK would create a query dictionary with a None parameters value, which would then be passed down to the HTTP request layer causing a TypeError: Session.request() got an unexpected keyword argument 'parameters'.

Solution:
Modified the query building logic in both sync and async container implementations to check if parameters has a non-None value before including it in the query structure. Now parameters=None is treated identically to omitting the parameter entirely, returning a simple query string instead of a dictionary with None values.

Changes:

• sdk/cosmos/azure-cosmos/azure/cosmos/container.py: Updated query building logic (lines 936-941)
• sdk/cosmos/azure-cosmos/azure/cosmos/aio/_container.py: Updated async query building logic (lines 824-829)

Impact:

• Fixes regression from version 4.9.0
• No breaking changes - all existing usage patterns remain unchanged
• Only affects the specific case where parameters=None is explicitly passed

Pull Request Overview

This PR refactors the query parameter handling logic in the query_items method for both synchronous and asynchronous container implementations. The change simplifies the condition for determining when to construct a parameterized query object by checking for parameter existence directly rather than using a utility function.

Key Changes:

• Replaced utils.valid_key_value_exist(kwargs, "parameters") with a direct parameters is not None check
• Extracted query and parameters values into intermediate variables before the conditional logic

[Nikhil172913832]

The failing test (test_read_items_concurrency_internals) seems unrelated to the changes in this PR.
My update only affects the query_items() method when parameters=None, and doesn't modify any of the read_items or concurrency internals.
Could you please re-run the CI to confirm if this failure is transient?
