chore(deps): bump openfeature-sdk to 0.10.0

[jonathannorris]

Summary

• Raises the openfeature-sdk floor in requirements.txt from ~= 0.8 to ~= 0.10.0
• Updates the OpenFeature docs and example to set_provider_and_wait(), since set_provider() is non-blocking in 0.10 and our initialize() timeout error no longer reaches the caller

Follow-up

track() isn't overridden on DevCycleProvider, so every client.track() call hits the base-class no-op and is silently discarded. Separate PR.

Pull request overview

Updates the SDK’s OpenFeature dependency to openfeature-sdk ~= 0.10.0 and aligns the documentation/examples with the newer provider initialization behavior by switching to api.set_provider_and_wait() so initialization failures surface to callers.

Changes:

• Bumped openfeature-sdk requirement from ~= 0.8 to ~= 0.10.0.
• Updated README and OpenFeature guide to recommend set_provider_and_wait() and explain the behavioral difference vs set_provider().
• Updated the OpenFeature example to use set_provider_and_wait() and handle GeneralError on initialization failure.
