feat: Migrate to the new template structure

[fmvilas]

Moves all the template files inside the template folder.

See asyncapi/generator#275

Summary of changes

• Moved everything that should/might be copied to the output directory to its own directory: "template".
• Moved .hooks, .partials, and .filters to the root directory, outside "template". And renamed those as "hooks", "partials", and "filters".
• Got rid of special file names like __README.md. They are not conflicting anymore so they're now README.md.

Something in this fix seemed to break the generator. I now get the error below, but if I point to my fork which doesn't have this PR merged it works fine.

That's weird. It's not failing for me. Are you sure you're on the latest version of the generator, @Mrc0113?

[Mrc0113]

Ah okay that was it. I thought I had the most recent since I just installed it 2 days ago, but apparently you're moving fast :)

[fmvilas]

Yeah, sorry. We're trying to push all the breaking changes now as we want to release v1.0.0 soon: https://github.com/asyncapi/generator/milestone/4.
