Updates azure-cosmos from 4.14.6 to 4.15.0

Release notes

Sourced from azure-cosmos's releases.

azure-cosmos_4.15.0

4.15.0 (2026-02-19)

Features Added

• GA support of Per Partition Automatic Failover and AvailabilityStrategy features.

Bugs Fixed

• Fixed bug where sdk was encountering a timeout issue caused by infinite recursion during the 410 (Gone) error. See PR 44770
• Fixed crash in sync and async clients when force_refresh_on_startup was set to None, which could surface as AttributeError: 'NoneType' object has no attribute '_WritableLocations' during region discovery when database_account was None. See PR 44987
• Fixed bug where unavailable regional endpoints were dropped from the routing list instead of being kept as fallback options. See PR 45200

Other Changes

• Added tests for multi-language support for full text search. See PR 44254
• Renamed availability_strategy_config introduced in 4.15.0b1 to availability_strategy for both sync and async clients. See PR 45086.
• Request-level availability_strategy needs to be set to False in order to disable availability strategy for that request, as opposed to setting it to None. See PR 45141.

azure-cosmos_4.15.0b2

4.15.0b2 (2025-12-16)

Bugs Fixed

• Fixed bug where sdk was not properly retrying requests in some edge cases after partition splits.See PR 44425

Looks like these dependencies are updatable in another way, so this is no longer needed.
