Integrate nginxreceiver (#9572)

* Add nginxreceiver factory to components

This enables using the nginxreceiver in the collector built from this
repo.

* Import nginxreceiver in components

* add replace rule for nginxreceiver in go.mod && make tidy

* update go.mod in cmd/configschema

First `make tidy` in the cmd/configschema module then add the replace
directive on receiver/nginxreceiver using the relative path.

* Add nginx check to receivers_test.go

* gofmt components.go

* Add nginx-receiver to go.mod in root and configcshema

* Add bug fix to CHANGELOG

* Remove errant linespace in receivers_test

* Require nginxreceiver v0.50.0 in go.mod
