chore: remove FDv2 pre-release warnings for GA promotion

FDv2 / data-saving mode is going GA per the SDK release-standards spec.
Removes the pre-release warning prose ("not stable, and not subject to
any backwards compatibility guarantees", "not suitable for production
usage", "You have been warned") from FDv2-related docstrings.
Descriptive docstrings are preserved.
