Support for writing Blood Pressure

[jim20926]

Currently, react-native-health provides getBloodPressureSamples to read blood pressure data, but there doesn’t seem to be any API to write blood pressure values back into HealthKit.

In iOS HealthKit, blood pressure is modeled as a Correlation type (HKCorrelationTypeIdentifierBloodPressure), which requires saving both a systolic and a diastolic quantity together.

Thank you so much to the maintainers and the community for building and maintaining this library 🙏.
It’s been really valuable for React Native projects. Adding support for blood pressure write functionality would make it even more complete.
