Current behavior

NestJs middlewares don't run when fastify is the HTTP adapter

When implementing fastify middleware from the docs: https://docs.nestjs.com/techniques/performance#middleware It doesn't run

Minimum reproduction code

https://stackblitz.com/edit/nestjs-typescript-starter-fvyxvn

Steps to reproduce

1. npm ci
2. npm start
3. Observe the middleware in main.ts runs but the LoggerMiddleware applied in the app.module.ts doesn't work.

Expected behavior

The logger middleware should work

Solution is

    consumer.apply(LoggerMiddleware).forRoutes('(.*)');

Default behaviour is different between express and fastify, this doesn't work for fastify:

    consumer.apply(LoggerMiddleware);

Not sure if I'm following. The provided code snippet:

consumer.apply(LoggerMiddleware);

is incorrect for both adapters.
