validate-modules: deprecated modules in collections (#68646)

* validate-modules: deprecated modules in collections

In Collections a module is marked as deprecated via meta/routing.yml

Use this file, rather than the leading `_` as part of the deprecated
test.

* Correct variable

* review comments

* indentation

* Read routing.yml only once

* pep8

* Apply suggestions from code review

Co-authored-by: Matt Clay <matt@mystile.com>

* review: remove duplicated conditional
