[FEATURE] Update nodejs-template for generator v3.x compatibility

[shivansh-source]

Why do we need this improvement?

Description

The @asyncapi/nodejs-template currently supports generator versions >=0.50.0 <2.0.0, making it incompatible with the latest generator v3.x.

I'm willing to work on this if the team is interested.

How will this change help?

Current Situation

• Current generator version: 3.1.2
• Template version range: >=0.50.0 <2.0.0
• Error when using: "This template is not compatible with the current version of the generator (3.1.2)"

Screenshots

Proposal

Update the template to support generator v3.x by:

1. Reviewing breaking changes in generator v3
2. Updating template code as needed
3. Updating version compatibility in package.json
4. Testing with generator v3.x

How could it be implemented/designed?
