Electron lists `eventLoopBlockIntegration` twice

[timfish]

The Electron docs have a specific page for Event loops blocked:
https://docs.sentry.io/platforms/javascript/guides/electron/configuration/event-loop-block/

And also list the Node specific integration:
https://docs.sentry.io/platforms/javascript/guides/electron/configuration/integrations/event-loop-block/

These should be conbined!
