Changes in this PR

The example in the docstring of ClientEncryption.rewrap_many_data_key passed the provider inside master_key, which raises ConfigurationError ("A provider must be given if a master_key is given"). The provider is now its own argument and master_key uses the fields of an Azure master key (keyVaultEndpoint, keyName) as documented in create_data_key. Docstring only. The synchronous copy was regenerated with tools/synchro.py. No changelog entry, as for earlier docstring fixes.

AI disclosure: I used an AI assistant (Claude Code) to help find the cause and write the fix. I read the change and I understand it.

Test Plan

Docs only, so no new test. I checked that the old example raises ConfigurationError and that the new one binds to the real signature and passes the argument checks. sphinx -W builds without warnings and the rendered example is correct. ruff, ruff format, the pre-commit hooks and the synchro self-test pass, and running tools/synchro.py again leaves a clean tree. The encryption tests that need KMS credentials cannot run in my environment, and the rewrap tests fail identically on main there.
