ts-node is registered if generator is imported in a .js file

[bakasmarius]

Describe the bug

ts-node is registered if @asyncapi/generator is simply imported in a file, even though the constructor or any other of generator's methods is not called at all.
This means that after building a TypeScript project, when it is transpiled to JavaScript, ts-node is still registered, even though TypeScript is not needed anymore.
This also means that ts-node is registered in a JavaScript project that does not use TypeScript at all.
We noticed it because after adding nestjs-asyncapi (which uses @asyncapi/generator) to one of our bigger projects, the startup time of npm start increased by ~30 seconds.

How to Reproduce

Create a new file test.js which only imports @asyncapi/generator and does nothing else with it:

const { REGISTER_INSTANCE } = require('ts-node');
console.log(process[REGISTER_INSTANCE] == null); // prints "true"
const generator = require('@asyncapi/generator');
console.log(process[REGISTER_INSTANCE] == null); // prints "false"

run node test.js and look at the output

Expected behavior

ts-node is registered only when it's actually needed.

This is the reason -> https://github.com/asyncapi/generator/blob/master/lib/generator.js#L59 -> https://github.com/asyncapi/generator/blob/master/lib/utils.js#L163

This is why it was added: #519

Any suggestions?

Looks like it would be enough to call this register function only if there are .ts files in:

• https://github.com/asyncapi/generator/blob/master/lib/filtersRegistry.js#L35
• https://github.com/asyncapi/generator/blob/master/lib/hooksRegistry.js#L37
