use proper intra doc link (#10271)

* use proper intra doc link

* use proper intra doc link

* get system path name from path module name function for the docs

* used format macro in formatting doc string for better output

* helper function to get intra doc string

* helper function to get intra doc string

* use helper function on expand_origin_pallet_conversions

* remove duplicates

* Update frame/support/procedural/src/construct_runtime/expand/origin.rs
