Add the version number to the output when wiremock starts

[leeturner]

This is a very simple PR to add the version number to the output when wiremock starts. I added it to the CommandlineOptions toString() method so the version is output regardless of whether the banner is enabled or not. I thought this might be better than adding the code in multiple places in the startup process. As far as I could tell there are no tests that validate the output of the startup process.

Output looks like this:

██     ██ ██ ██████  ███████ ███    ███  ██████   ██████ ██   ██ 
██     ██ ██ ██   ██ ██      ████  ████ ██    ██ ██      ██  ██  
██  █  ██ ██ ██████  █████   ██ ████ ██ ██    ██ ██      █████   
██ ███ ██ ██ ██   ██ ██      ██  ██  ██ ██    ██ ██      ██  ██  
 ███ ███  ██ ██   ██ ███████ ██      ██  ██████   ██████ ██   ██
