👌🏻 Allow ServiceMatcher to be injected

[yoan-myparcel]

This pull request introduces the ServiceMatcher dependency into the MyParcelComApi class to improve service matching during API operations. The most important changes include adding the ServiceMatcher as a private member, updating constructors and methods to handle this dependency, and refactoring the getServices method to utilize the new ServiceMatcher instance.

Dependency Injection and Refactoring:

• src/MyParcelComApi.php: Added ServiceMatcher as a private member to the MyParcelComApi class.
• src/MyParcelComApi.php: Updated the createSingleton method to accept an optional ServiceMatcher parameter and pass it to the constructor.
• src/MyParcelComApi.php: Modified the constructor to accept an optional ServiceMatcher parameter and set it using a new setServiceMatcher method. [1] [2]
• src/MyParcelComApi.php: Refactored the getServices method to use the instance of ServiceMatcher instead of creating a new one.
• src/MyParcelComApi.php: Added a setServiceMatcher method to allow setting the ServiceMatcher instance.
