feat(core): Improve paired item and add additional variables (#3765)

*  Remove duplicate and old string

*  Add telemetry

*  Futher improvements

*  Change error message and display only name of last parameter

* 👕 Fix lint issue

*  Remove not needed comments

*  Rename properties, add new ones and improve error messages

*  Add support for $execution, $prevNode and make it possible to use proxies as object

*  Some small improvements

* 🐛 Fix error message

*  Improve some error messages

*  Change resumeUrl variable and display in editor

*  Fix and extend tests

*  Multiple pairedItem improvements

*  Display "More Info" link with error messages if user can fix issue

*  Display different errors in Function Nodes
