Postman Collection can't be imported

[BirgitSaalfeld]

Problem
Import of both current Postman collections https://github.com/ehrbase/documentation/tree/master/examples leads to an error message:
Error while importing: format not recognized
An old version I got from Pascal Bierman works.

Definition of done
Importable collection

@BirgitSaalfeld I was able to import the current format in Postman 8+

I'm working on updating the file with more examples https://github.com/ehrbase/project_management/issues/582
