Unable to load the referenced json schema

### Which Data Mapper Version are you using ?

v2

### Describe the Bug with repro steps

- There are 2 schemas Contact.json and External.json, where the first one has a relative reference to the second one (the both were preloaded into the Azure Logic Apps (Standard) Schemas folder and provided in the additional context).
- Create a new Data Map
- Select the existing External.json schema -> it is successfully loaded to show only the "root*" element (it is only an experiment to see if this schema can be found and is valid)
- Select the existing Contact.json schema -> it failed to be loaded "400 - InvalidSchema: The provided schema content is not valid. If the schema has any references, please upload the referenced schema to the Integration Account first. The compilation of schema failed with error: 'Could not resolve schema reference 'http://integration/schemas/External.json#/$defs/Date'. Pass '', line 13, position 24.'." (as specified above this schema was preloaded into the Schemas folder and validated in the previous step).
