switch get_thumb to use context.wrap_socket

switch get_thumb to use context.wrap_socket
due to removal of ssl.wrap_socket in python 3.12
fixed mixed indentation and mixed variable naming to snake case, as per python standard

This fixes #517

Tested as working in my lab

@ggverma can you please prioritise merging this, as these modules do not work using recent versions of Linux, including Ubuntu 24.04.

I noticed that ssl.wrap_socket() is also used in plugins/modules/nsxt_transport_nodes.py, specifically within the get_api_cert_thumbprint() function.
Because of this, ansible-for-next does not work with Python 3.12, and as a result, it also fails to run on Ubuntu 24.04. Since this module doesn't work on the latest OS versions, I believe we should consider raising the priority of this issue.
