First stable release 🥳

This release contains the work done to:

• configured this library and put into place the necessary tools to improve working on the library;
• hand-crafted the Open API specification document to represent the Marvel Comics API online service, so a client and any input/output types can be generated dynamically;
• implemented an authorization middleware that authorizes every request send to the online service;
• fixed some issues encountered in Swift 5.10 and Swift 6, plus issues encountered when building the library on non-Apple platforms;
• fixed some issues encountered at endpoints and types definitions in the OpenAPI specification document;
• generated the Github Pages documentation out of the DocC documentation in the library;
