ConflictResolutionStrategy docstring documents a NONE member that the enum does not define

Describe the bug

The ConflictResolutionStrategy docstring documents a NONE member that the enum does not define.

At commit 5e2fcea990aa3b99660d2aea9121d0ba74a8940b, presidio-anonymizer/presidio_anonymizer/entities/conflict_resolution_strategy.py:

• line 15 (in the class docstring): NONE: No conflict resolution will be performed.
• lines 18-19 (the members): MERGE_SIMILAR_OR_CONTAINED and REMOVE_INTERSECTIONS only.

There is also no code path that performs no conflict resolution: in anonymizer_engine.py, the merge and conflict passes in _remove_conflicts_and_get_text_manipulation_data run unconditionally, and only REMOVE_INTERSECTIONS is gated (line 196).

To Reproduce

from presidio_anonymizer.entities import ConflictResolutionStrategy

ConflictResolutionStrategy.NONE  # AttributeError: NONE

Why it matters

A caller who follows the docstring and passes ConflictResolutionStrategy.NONE to AnonymizerEngine.anonymize gets an AttributeError, and the docstring implies an opt-out from conflict resolution that the engine does not offer.

Suggested fix

Delete line 15 from the docstring. If a no-op strategy is actually intended, the alternative is to add the member and return early from _remove_conflicts_and_get_text_manipulation_data when it is selected, but that is a behaviour change rather than a docs fix.

Additional context

Found while evaluating Presidio as a reference detector for a browser DLP extension.
