fix(discovery): support NestJS 11 (#945)

* fix(deps): update nest monorepo to v11

* fix(discovery): support NestJS 11

From NestJS 11, InstanceWrapper.metatype can be null. Mapping it from `null` to `undefined` for
`DiscoveredClass.injectType` to avoid a breaking change.

#944

* fix(discovery): discoveredClass.injectType can be null

Support both undefined and null while supporting NestJS 10 and 11.
