fix: Use addExposedPort instead of setExposedPort which overrides user configuration

[TheRealGuru]

…r configuration

Currently it is impossible to configure SSL, rather than go through all the hoops to add proper configuration for SSL I've applied this hotfix. By using addExposedPort we do not override the user configuration. Currently if I was to do the following:

  WireMockContainer wiremockServer = new WireMockContainer("wiremock/wiremock:2.35.0").withExposedPorts(8443);

This would never bind 8443 because when the container is started the configure also calls withExposedPorts, therefore overriding the user configured values.

This means we cannot configure SSL as we need a port for HTTP and HTTPS.

For testing I simply exposed an additional port to test that this would no longer override that port - this test if tried without the code change will fail. This confirms that the code is working as expected.
