generator feat: add hooks library to generator

Resolves https://github.com/asyncapi/generator/issues/1270

I added inline comments for some more context on the PR

What this PR does? from the changeset:

Package @asyncapi/generator-hooks is now part of generator repo and won't be released separately. Source code is stored under apps/hooks but the package/library name stays as it was originally for backward compatibility,
By default @asyncapi/generator-hooks package, known as package with a lot of different hooks used in templates, is available in the generator and you no longer have to configure it in your package.json in dependencies. Package @asyncapi/generator-hooks will no longer be published to NPM separately and is deprecated. You can still have your own hooks, and you can still store them in a separate package and configure with your template,
Remember that the fact that hooks package is now included by default, doesn't mean all hooks from it are enabled by default. You still have to enable given hook in the configuration explicitly because some hooks can execute automatically without passing a specific parameter. Also hook's supported parameters also need to be defined in your template's config.

Also, next steps after it is merged:
