fix(core): Pass module into loadModule (#15139)

The `loadModule` function currently utilizes `require` to load modules
starting from the `@sentry/core` directory. This approach is
incompatible with package managers like pnpm, which do not hoist
dependencies. Consequently, when another module, such as @sentry/nextjs,
invokes `loadModule`, it fails to locate its own dependencies because
the search initiates within the @sentry/core tree.
