Resolve references in pdf generated document

[AnyFlyGuy]

Bug description

Currently the tool, which generates the PDF can't resolve references to the other OpenAPI specification and will display {recursive} instead.

Potential suggestion for fix

Create a script, which:

• creates a temporary copy of the kms server OpenAPI specification
• modifies temporary copy and append the schemes from the qkd server OpenAPI specification
• resolves $ref links to point to local file, not the other file
• create pdf from the temporary copy.
