fix: avoid crash when printing help in wiremock-standalone

[tomasbjerre]

Supplying relocated properties to avoid crash when they are read from relocated joptsimple when using wiremock-standalone.

In Wiremock 3.0.0 and 3.0.1 if you do:

java -jar wiremock-standalone-3.0.1.jar --help

You will get:

Exception in thread "main" java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key wiremock.joptsimple.BuiltinHelpFormatter.option.header

I tried adding a test case for this. Since the problem happens after relocation, I was unable to.
