great work @kaushik-rishi

we need to do breaking change as 3658766 had to be done, to make sure generator with react engine is required. I also made sure to require minimum 1.15 that is the first version enabling v3 that you anyway need

2 followup changes are needed, in separate PR:

• template/README.md.js has outdated instructions
• https://github.com/asyncapi/nodejs-template/?tab=readme-ov-file#how-to-use-the-template is also outdated, npm start no longer makes sense. So combine some of the steps (but use AsyncAPI CLI) with https://github.com/asyncapi/nodejs-template/?tab=readme-ov-file#adding-custom-code--handlers that are fine - so it is end to end copy paste instruction
• maybe it makes sense to have script from Adding custom code / handlers section actually stored in test and have a script that starts it, like npm run example
