feat: Refactor VM object to inherit from Host

[KTokarze]

This pull request refactors the VM class in mfd_hyperv/instances/vm.py to inherit from the Host class, adjusts its initialization logic to bypass the Host factory pattern, and makes several minor documentation and code improvements. The changes improve code reuse, maintainability, and clarity.

Class inheritance and initialization refactor:

• Updated the VM class to inherit from Host and overrode the __new__ method to bypass the Host factory pattern for VM instances. The constructor now calls super().__init__, passing the connection and any additional keyword arguments. This enables better code reuse and integration with the Host class while maintaining the specific instantiation logic required for VMs. [1] [2] [3]

Documentation and readability improvements:

• Fixed typos and clarified docstrings for methods and properties, such as correcting "untill" to "until" and standardizing the spelling of "HyperV" and "vNICs" in property and parameter descriptions. [1] [2] [3] [4]
