feat(core)!: Remove addOpenTelemetryInstrumentation method

[AbhiPrasad]

Deprecation PR: #14485

The addOpenTelemetryInstrumentation method has been removed. Use the openTelemetryInstrumentations option in Sentry.init() or your custom Sentry Client instead.

import * as Sentry from '@sentry/node';

// before
Sentry.addOpenTelemetryInstrumentation(new GenericPoolInstrumentation());

// after
Sentry.init({
  openTelemetryInstrumentations: [new GenericPoolInstrumentation()],
});
