MAINTAINERS: adjust the file entry in GOCONTROLL MODULINE MODULE SLOT

Commit 8f1cc524 ("MAINTAINERS: add maintainer for the GOcontroll
Moduline module slot") adds a new MAINTAINERS section referring to the
non-existent file:
  Documentation/connector/gocontroll,moduline-module-slot.yaml

It intends to refer to the file with the same name in
Documentation/devicetree/bindings/connector/. Adjust the file reference to
the intended location.
