Make fs instrumentation follow semantic conventions

### Description

See https://opentelemetry.io/docs/specs/semconv/attributes-registry/file/

https://github.com/getsentry/sentry-javascript/blob/bdbdcc87b8816d439740395dcc551e5289e4431d/packages/node/src/integrations/fs.ts#L52 sets non namespaced attributes that don't follow conventions. We should see if we can set those as appropriate, and or contribute upstream to improve the conventions.
