Potential Commit/PR that introduced the regression

#13493

NestJS version

10.3.9

Describe the regression

Previously a HEAD request used to respond with status 200. Now it responds with a 404.

Minimum reproduction code

repoduction repo

Input code

curl -I http://localhost:3000

Expected behavior

Status 200 if the endpoint exists

Other

The new Fastify route(...) supports an array of HTTP methods. The simplest solution might be to just inject routes with method: [method, 'HEAD']

This is currently breaking all our UptimeRobot monitors (since they use HEAD to check for a 200).
